👥 500 troops deployed

📅 3,650 days of conflict

The Yemen War (2015-present) represents the most consequential and least understood American military involvement of the 21st century. Since March 2015, the United States has served as the primary enabler of a Saudi Arabian-led coalition bombing campaign that has killed an estimated 377,000 people — 60% from indirect causes including famine, disease, and lack of medical care — and created what the United Nations has called the world's worst humanitarian crisis. American involvement includes 4.6 billion in arms sales to Saudi Arabia and the UAE, mid-air refueling of Saudi bombers (until November 2018), sharing of targeting intelligence, maintenance of Saudi aircraft, naval support for the coalition's blockade, and diplomatic cover at the United Nations Security Council. U.S.-manufactured bombs and aircraft have been documented striking hospitals, schools, weddings, funerals, water treatment facilities, and a school bus carrying 40 children. Despite bipartisan congressional opposition — including passage of a War Powers Resolution to end U.S. involvement that was vetoed by President Trump — American support has continued through four presidential administrations (Obama, Trump, Biden, and Trump again). The war has no congressional authorization, serves no vital American national security interest, and has demonstrably violated U.S. laws prohibiting arms transfers to countries that systematically target civilians.

The Full Story

How this conflict unfolded

The Yemen war is the definitive case study in how the United States enables catastrophic violence while maintaining the fiction of non-involvement. For nearly a decade, American-manufactured weapons dropped from American-built aircraft, guided by American intelligence, refueled by American tankers, and maintained by American contractors have killed tens of thousands of Yemeni civilians and created the worst humanitarian crisis on earth. Yet the war is barely known to the American public, has never been authorized by Congress, and continues through multiple administrations of both parties.

The war's origins lie in Yemen's failed political transition after the 2011 Arab Spring. When the Houthi movement, a Zaidi Shia revivalist group from northern Yemen, seized the capital Sana'a in September 2014 in alliance with forces loyal to former President Ali Abdullah Saleh, Saudi Arabia viewed it as an intolerable expansion of Iranian influence on its southern border. On March 26, 2015, Saudi Deputy Crown Prince Mohammed bin Salman — 29 years old, with no military experience — launched Operation Decisive Storm, projecting a campaign lasting "a few weeks."

The Obama administration immediately signed on as the Saudi coalition's indispensable partner. Within days, the Pentagon established a joint planning cell at Saudi Arabia's air operations center in Riyadh, embedding American military personnel who assisted with target selection and intelligence. U.S. Air Force tankers began refueling Saudi F-15s before bombing missions. American-manufactured precision-guided munitions, cluster bombs, and general-purpose bombs flowed to Saudi Arabia through expedited arms sales. The State Department approved billions in weapons transfers with minimal scrutiny.

The decision to support the Saudi war was made without public debate, congressional authorization, or strategic justification. Yemen poses no threat to the United States. The Houthis, while receiving some Iranian support, are not an Iranian proxy in any meaningful sense — they are a Yemeni movement with Yemeni grievances. The primary U.S. motivation was maintaining the Saudi relationship and the massive arms sales that sustain it. Between 2015 and 2024, U.S. arms sales to Saudi Arabia totaled approximately 4.6 billion — a revenue stream that creates powerful corporate and bureaucratic constituencies for continued support regardless of humanitarian consequences.

The human cost has been beyond anything the euphemistic language of "supporting our allies" can capture. The Saudi coalition's air campaign has systematically struck civilian infrastructure: hospitals, schools, water treatment plants, sewage facilities, bridges, power stations, food storage, and ports. These are not collateral damage from strikes on military targets — multiple investigations by the UN, Human Rights Watch, Amnesty International, and journalists have documented a pattern of deliberate or recklessly indiscriminate targeting of civilian facilities.

The individual atrocities are numbing in their frequency and horror. In October 2016, coalition aircraft conducted a double-tap strike on a funeral in Sana'a, killing 140 mourners and wounding 500. In August 2018, a coalition bomb hit a school bus in Dahyan, killing 40 children — the bomb was identified as a U.S.-manufactured MK 82 made by Lockheed Martin, sold through a State Department-approved deal. MSF-supported hospitals were struck at least five times despite the coalition having GPS coordinates for every facility. Wedding parties, markets, residential neighborhoods — the bombing has been relentless and indiscriminate.

The blockade has been even more lethal than the bombing. Yemen imports 90% of its food, and the Saudi-led coalition's naval and air blockade has systematically restricted imports through the port of Hodeidah, through which 70% of Yemen's supplies flow. The result is the world's worst famine: an estimated 85,000 children under five died of starvation between 2015 and 2018 alone. The destruction of water infrastructure triggered the largest cholera epidemic in recorded history — over 2.5 million cases. The UN estimates that 377,000 people had died by the end of 2021, with 60% of deaths from indirect causes: starvation, disease, and the collapse of the healthcare system.

The Khashoggi murder in October 2018 briefly pierced the wall of American indifference. The Saudi regime's assassination and dismemberment of Washington Post columnist Jamal Khashoggi inside the Saudi consulate in Istanbul — personally ordered by MBS according to U.S. intelligence — forced a reckoning with the character of the ally the U.S. was arming. But the reckoning was short-lived: the Trump administration declined to impose meaningful consequences, and arms sales continued.

Congress, to its credit, attempted to assert its constitutional authority. In March 2019, both chambers passed a War Powers Resolution directing the president to withdraw U.S. forces from the Yemen conflict — the first successful invocation of the War Powers Act since its passage in 1973. Trump vetoed the resolution. Congress failed to override. The episode demonstrated the constitutional impotence of the legislative branch in matters of war: even bipartisan majorities cannot halt presidential war-making when the executive is determined to continue.

Biden's February 2021 pledge to end U.S. support for "offensive operations" in Yemen was carefully crafted to change the rhetoric while preserving the substance of American involvement. The U.S. stopped providing aerial refueling (which had actually ended under Trump in 2018) and suspended some precision-guided munition sales. But intelligence sharing continued. Aircraft maintenance and spare parts contracts continued. "Defensive" arms sales — including the systems that enable the bombing campaign — continued. The distinction between "offensive" and "defensive" support is a legal fiction: you cannot separate the bullets from the gun.

The war's strategic futility is now undeniable. Nearly a decade of bombing, at a cost of hundreds of billions to the Saudi treasury, has achieved nothing. The Houthis control more territory and possess more military capability than when the war began. Their 2023-2024 attacks on Red Sea shipping demonstrated the ability to project force across an entire region — something they could not do in 2015. The U.S. and UK are now bombing Yemen directly, having created the conditions for the very threat they claim to be addressing.

The 4.6 billion in U.S. arms sales that fueled the war dwarfs the humanitarian aid provided to address the catastrophe those weapons created. Lockheed Martin, Raytheon, Boeing, and General Dynamics have profited enormously from the conflict. The Saudi relationship — built on petrodollars, arms sales, and geopolitical convenience — has proven more valuable to American policymakers than the lives of Yemeni children.

Yemen reveals the structural incentives that make American war-making so difficult to stop. The arms industry profits from weapons sales. The executive branch values the Saudi alliance. The military provides support as a matter of institutional routine. Congressional opposition is structurally insufficient to overcome a presidential veto. The American public is largely unaware of the war and its consequences. Each element of the system has its own logic; together they produce a machine that enables mass killing with no mechanism for accountability or restraint.

The 377,000 dead, the 85,000 starved children, the 2.5 million cholera cases, the generation of traumatized and malnourished survivors — these are not the unintended consequences of American policy. They are the predictable and predicted results of a deliberate decision to arm and support a military campaign against one of the poorest countries on earth, made by officials who understood exactly what would happen and chose to proceed because the Saudi relationship was deemed more important than Yemeni lives. That is not a failure of policy. It is the policy working as designed.

📊Where The Money Went

Total U.S. involvement cost: approximately 4.6 billion in arms sales plus 0+ billion in direct military support costs. Arms sales (2015-2024): approximately 4.6 billion in weapons transfers to Saudi Arabia and the UAE, including F-15SA fighter jets (9.4 billion deal in 2010, delivered during the war), MK 82 and MK 84 general-purpose bombs, Paveway precision-guided munition kits, JDAM guidance systems, AGM-84 Harpoon missiles, M1 Abrams tanks, Apache helicopters, and ammunition. Major defense contractors: Lockheed Martin (F-15s, Paveway kits, THAAD), Boeing (F-15 components, JDAM kits, Apache helicopters), Raytheon (Paveway, air-to-air missiles), and General Dynamics (ammunition, bomb bodies). Direct military support: approximately -3 billion in aerial refueling operations (~9,000 sorties 2015-2018), intelligence sharing and satellite imagery, joint planning cell personnel at Saudi CAOC, naval operations supporting the blockade, and aircraft maintenance contracts. AQAP counter-terrorism operations in Yemen: approximately -3 billion for drone strikes, special operations raids, and intelligence operations against al-Qaeda in the Arabian Peninsula. Humanitarian aid: the U.S. has provided approximately billion in humanitarian assistance to Yemen — less than 10% of the arms sales value that created the crisis. The ratio of weapons-to-aid spending encapsulates the moral calculus of U.S. Yemen policy.

🚨 Constitutional Violation

Article I, Section 8 of the Constitution grants Congress the exclusive power to declare war. This conflict proceeded without proper authorization, violating the separation of powers.

🏛️Constitutional Context

This conflict was waged without congressional authorization — a violation of Article I, Section 8 of the Constitution, which vests the war power exclusively in Congress. No congressional authorization. Congress voted to end support in 2019; Trump vetoed. Biden pledged to end but continued. The Founders deliberately gave Congress the war power to prevent exactly this kind of executive adventurism. As James Madison wrote: "The executive has no right, in any case, to decide the question, whether there is or is not cause for declaring war."

Timeline of Events

Key moments that shaped this conflict

🚀

Houthi movement emerges from northern Yemen's Sa'dah Wars (2004-2010) — The Houthis, officially known as Ansar Allah (Supporters of God), originate as a Zaidi Shia revivalist movement in northern Yemen's Sa'dah governorate. Named after their founder Hussein Badreddin al-Houthi (killed 2004), the movement fights six wars against Yemen's central government between 2004 and 2010. The Houthis accuse the Yemeni government of corruption, marginalization of the north, and complicity with Saudi and American interference. Iran provides limited support, though the degree of Iranian influence is disputed — U.S. and Saudi claims of Houthi-Iran coordination are frequently exaggerated.

📍

Arab Spring protests and political transition in Yemen (2011-2014) — Mass protests force President Ali Abdullah Saleh, who had ruled Yemen for 33 years, to resign in February 2012 under a GCC-brokered transition deal. Vice President Abd Rabbuh Mansur Hadi assumes power and launches a National Dialogue Conference. However, the transition process fails to address underlying grievances, economic conditions deteriorate, and Hadi's government proves weak and corrupt. The Houthis, excluded from meaningful power-sharing, begin expanding southward from Sa'dah.

📍

Houthis capture Sana'a with tacit Saleh alliance (September 21, 2014) — Houthi forces, in an unlikely alliance with forces loyal to former President Saleh, seize the capital Sana'a with minimal resistance. The Houthis quickly dissolve parliament and establish a revolutionary committee. President Hadi flees first to Aden, then to Riyadh. The takeover alarms Saudi Arabia and the Gulf states, who view the Houthi movement as an Iranian proxy threatening their southern border.

📍

Saudi Arabia launches Operation Decisive Storm (March 26, 2015) — Saudi Arabia's young Deputy Crown Prince Mohammed bin Salman (age 29) announces a military coalition of nine Arab states to restore Hadi's government and counter Iranian influence. The operation begins with massive airstrikes on Houthi positions in Sana'a and across northern Yemen. MBS projects the campaign will last "a few weeks." The Obama administration provides immediate support: intelligence sharing, targeting assistance, mid-air refueling, and expedited weapons deliveries. The U.S. role is not publicly debated or authorized by Congress.

📍

Obama administration establishes Joint Planning Cell with Saudi military (2015) — The Pentagon creates a joint coordination cell at Saudi Arabia's Combined Air Operations Center in Riyadh, embedding American military personnel who assist with target selection, provide intelligence, and help plan air operations. The U.S. military insists this is to help reduce civilian casualties; critics argue it makes the U.S. directly complicit in targeting decisions. American personnel are reportedly present during strike planning for operations that subsequently hit civilian targets.

📍

Médecins Sans Frontières (MSF) hospitals struck repeatedly (2015-2016) — Saudi coalition airstrikes hit MSF-supported medical facilities at least five times in 2015-2016, including the Haydan hospital in Sa'dah (October 2015), the Shiara hospital in Razeh (January 2016), and Abs hospital in Hajjah (August 2016). MSF provides the GPS coordinates of all its facilities to the coalition in advance. The repeated strikes on clearly marked medical facilities suggest either deliberate targeting or reckless disregard for civilian protection. MSF evacuates staff from several hospitals.

📍

Saudi airstrike on funeral hall in Sana'a kills 140 (October 8, 2016) — Coalition aircraft conduct a "double-tap" strike on a funeral ceremony at the Great Hall in Sana'a, killing at least 140 mourners and wounding over 500. The funeral is attended by senior political and military figures. The attack, one of the deadliest single incidents of the war, prompts the Obama administration to announce a review of U.S. support — but arms sales and military assistance continue. A Joint Incidents Assessment Team (JIAT) investigation, led by Saudi Arabia itself, later acknowledges the strike was based on "incorrect information."

📍

Obama approves 15 billion in arms sales to Saudi Arabia (2009-2016) — Over his two terms, President Obama authorizes more weapons sales to Saudi Arabia than any previous administration, including F-15 fighter jets, Apache helicopters, armored vehicles, bombs, and missiles. A significant portion of these weapons are used in Yemen. In December 2016, after the funeral hall bombing, Obama suspends the sale of precision-guided munitions — the only meaningful restriction imposed during his presidency. The suspension is reversed by Trump within months of taking office.

📍

Cholera epidemic becomes largest in recorded history (2016-2019) — The destruction of water and sanitation infrastructure by coalition bombing, combined with the blockade that restricts fuel imports needed for water pumping and sewage treatment, triggers a cholera epidemic that infects over 2.5 million Yemenis — the largest cholera outbreak in recorded history. Over 4,000 people die from a disease that is easily preventable with clean water and basic sanitation. The epidemic represents a direct consequence of the coalition's systematic destruction of civilian infrastructure.

📍

Famine conditions: 85,000 children under five die of starvation (2015-2018) — Save the Children estimates that 85,000 Yemeni children under the age of five have died of famine and disease between 2015 and 2018. The Saudi-led coalition's naval and air blockade severely restricts food imports to a country that depends on imports for 90% of its food supply. The port of Hodeidah, through which 70% of Yemen's imports flow, is repeatedly bombed and blockaded. UNICEF calls Yemen "the largest humanitarian crisis in the world" and warns that an entire generation of Yemeni children faces starvation, disease, and developmental damage.

⚔️

Saudi coalition bombs school bus in Dahyan, killing 40 children (August 9, 2018) — A Saudi airstrike hits a school bus carrying students on a field trip in Dahyan, Saada governorate, killing 40 children and 11 adults. The bomb is identified as a U.S.-manufactured MK 82 guided bomb made by Lockheed Martin, sold to Saudi Arabia through a State Department-approved arms deal. Photographs of the bomb fragment with American markings are published worldwide, becoming an iconic image of U.S. complicity. CNN's investigation identifies the specific arms deal that supplied the weapon. The strike generates unprecedented public outrage in the United States and Europe.

📍

U.S. ends mid-air refueling of Saudi aircraft (November 2018) — Following the Dahyan school bus bombing and the murder of journalist Jamal Khashoggi, the U.S. military ends aerial refueling support for Saudi coalition aircraft conducting strikes in Yemen. The refueling had been provided continuously since March 2015, with U.S. Air Force KC-135 and KC-10 tankers refueling Saudi F-15s and Emirati aircraft before bombing missions. The Pentagon reveals that it had provided approximately 9,000 refueling sorties over three years. However, other forms of support — intelligence sharing, weapons sales, aircraft maintenance, and spare parts — continue.

📍

Murder of journalist Jamal Khashoggi exposes Saudi impunity (October 2, 2018) — Saudi agents murder and dismember Washington Post columnist Jamal Khashoggi inside the Saudi consulate in Istanbul. U.S. intelligence concludes that Crown Prince Mohammed bin Salman personally ordered the killing. The assassination of a journalist resident in the United States triggers global outrage and intense scrutiny of the U.S.-Saudi relationship, including the Yemen war. Despite the intelligence assessment, the Trump administration refuses to impose meaningful consequences on MBS, prioritizing arms sales and the Saudi relationship. The Khashoggi murder crystalizes the moral cost of the U.S.-Saudi partnership.

📍

Senate passes War Powers Resolution to end U.S. Yemen involvement (March 2019) — In a historic vote, the U.S. Senate passes S.J.Res.7, a War Powers Resolution directing the president to withdraw U.S. forces from hostilities in Yemen not authorized by Congress. The resolution passes 54-46 with bipartisan support, marking the first time either chamber has passed a War Powers Resolution to end a military engagement since the act was passed in 1973. The House passes a similar resolution 247-175. President Trump vetoes the resolution on April 16, 2019, and Congress fails to override. The episode demonstrates that even bipartisan congressional majorities cannot halt presidential war-making.

📍

Trump vetoes congressional attempts to block Saudi arms sales (July 2019) — After the Khashoggi murder and continued civilian casualties in Yemen, Congress passes multiple resolutions blocking specific arms sales to Saudi Arabia and the UAE. Trump vetoes all of them, declaring a state of emergency to circumvent congressional review under the Arms Export Control Act. Secretary of State Pompeo certifies that Saudi Arabia is taking steps to reduce civilian casualties — a certification that career State Department officials refuse to sign, leading to an inspector general investigation.

📍

Biden pledges to end U.S. support for Yemen war (February 2021) — President Biden announces that the United States will end support for "offensive operations" in the Yemen war, including the sale of precision-guided munitions to Saudi Arabia. Biden calls the Yemen war a humanitarian and strategic catastrophe. However, the policy contains significant carve-outs: "defensive" arms sales continue, intelligence sharing is maintained, and the U.S. continues providing aircraft maintenance and spare parts that keep Saudi warplanes flying. Critics argue that the distinction between "offensive" and "defensive" support is meaningless when both enable the same bombing campaign.

📍

UN estimates 377,000 total deaths in Yemen by end of 2021 — The United Nations Development Programme releases a comprehensive study estimating that 377,000 people have died in the Yemen conflict through 2021 — approximately 60% from indirect causes including food insecurity, disease, and lack of healthcare. The report projects that if the war continues, deaths could reach 1.3 million by 2030. The total death toll makes Yemen one of the deadliest conflicts of the 21st century, with the U.S. as the primary external enabler.

📍

Saudi-Houthi truce and diplomatic opening (April 2022-2023) — A UN-brokered truce takes effect in April 2022, significantly reducing airstrikes and civilian casualties. Saudi Arabia, exhausted by nearly a decade of war and seeking to improve its international image, engages in Chinese-brokered diplomatic talks with Iran. The truce formally expires in October 2022 but an informal cessation of major hostilities continues. The diplomatic opening suggests that the war could have been ended through negotiation years earlier, sparing hundreds of thousands of lives.

📍

Houthis attack Red Sea shipping, U.S. launches Operation Prosperity Guardian (October 2023-present) — In response to Israel's war in Gaza, Houthi forces begin attacking commercial shipping in the Red Sea, claiming solidarity with Palestinians. The attacks disrupt global trade through the Suez Canal. The U.S. and UK launch airstrikes against Houthi targets in Yemen under Operation Prosperity Guardian, marking a new phase of direct American military engagement. The Houthi attacks demonstrate that nearly a decade of Saudi bombing, supported by the U.S., failed to degrade Houthi military capabilities — they are now stronger and better armed than when the war began.

📍

U.S. re-designates Houthis as terrorist organization (January 2024) — The Biden administration redesignates the Houthi movement as a Specially Designated Global Terrorist organization in response to Red Sea attacks. The designation, previously imposed and then revoked, threatens to further restrict humanitarian aid to Houthi-controlled areas where millions of Yemenis depend on international assistance for survival. Aid organizations warn the designation will worsen the humanitarian crisis.

🏁

Yemen war enters its tenth year with no resolution (2025) — The conflict continues with no comprehensive peace agreement. Saudi Arabia has largely stopped bombing but seeks a face-saving exit. The Houthis control most of Yemen's population centers and have demonstrated the ability to project military force across the region. The humanitarian catastrophe persists: 21.6 million Yemenis (two-thirds of the population) need humanitarian assistance, and the country's infrastructure, healthcare system, and economy have been devastated. The U.S. has spent an estimated 4.6 billion in arms sales to Saudi Arabia and the UAE that fueled the war, while providing only a fraction of that amount in humanitarian aid to address the crisis those weapons created.

🎯 Objectives (Not Met / Partially Met)

  • Support Saudi Arabia against Houthis
  • Counter Iranian influence

A U.S.-made MK 82 bomb killed 40 children on a school bus in Dahyan, Yemen in August 2018 — the bomb fragment with American markings was photographed and shared worldwide.

2

Yemen has experienced the largest cholera outbreak in recorded history — over 2.5 million cases since 2016 — largely because Saudi bombing destroyed water and sanitation infrastructure.

3

An estimated 85,000 Yemeni children under five have died of famine as a result of the Saudi-led blockade supported by the U.S.

4

The U.S. has provided mid-air refueling for Saudi bombers, shared targeting intelligence, sold billions in bombs and fighter jets, and provided diplomatic cover at the UN — essentially fighting the war by proxy.

5

Congress passed a bipartisan War Powers Resolution to end U.S. support for the Yemen war in 2019 — Trump vetoed it, and the involvement continued.

6

Saudi Arabia's crown prince Mohammed bin Salman launched the Yemen war in 2015 when he was 29 years old, projecting it would last a few weeks. It has lasted nearly a decade.

7

The UN estimates that 377,000 people died in the Yemen conflict by the end of 2021 — approximately 60% from indirect causes including famine, disease, and lack of healthcare rather than direct violence.

8

U.S. arms sales to Saudi Arabia totaled approximately 4.6 billion between 2015 and 2024, creating a massive corporate constituency (Lockheed Martin, Raytheon, Boeing, General Dynamics) for continued support regardless of humanitarian consequences.

9

The U.S. military provided approximately 9,000 aerial refueling sorties for Saudi coalition aircraft between 2015 and 2018, directly enabling bombing missions that struck civilian targets.

10

Save the Children estimated that 85,000 Yemeni children under five died of famine and disease between 2015 and 2018 — the equivalent of every child in a mid-sized American city.

11

Career State Department officials refused to sign Secretary Pompeo's certification that Saudi Arabia was taking steps to reduce civilian casualties, leading to an inspector general investigation. The IG was fired before completing the probe.

12

Yemen imports 90% of its food. The Saudi-led blockade of Hodeidah port, supported by the U.S. Navy, deliberately restricted food imports as a weapon of war — a potential violation of international humanitarian law.

13

Former President Ali Abdullah Saleh, who initially allied with the Houthis, switched sides and attempted to negotiate with the Saudi coalition. The Houthis killed him on December 4, 2017, demonstrating the fluid and treacherous nature of Yemeni factional politics.

14

The Houthis' 2023-2024 Red Sea attacks on commercial shipping proved that nearly a decade of Saudi bombing, enabled by the U.S., failed to degrade Houthi military capabilities — they are now stronger than when the war began.

Controversy #7

The Joint Incidents Assessment Team (JIAT), tasked with investigating civilian casualty incidents, was led by Saudi Arabia itself — making the perpetrator responsible for investigating its own crimes. The JIAT consistently minimized or denied civilian harm.

Controversy #8

The Khashoggi connection: the same Saudi regime that murdered and dismembered a journalist in its own consulate is the regime the U.S. has armed to conduct the Yemen war. U.S. intelligence confirmed MBS ordered the killing, yet arms sales continued.

Biden's February 2021 pledge to end "offensive" support maintained intelligence sharing, aircraft maintenance, spare parts, and "defensive" arms sales — preserving the substance of U.S. involvement while changing the rhetoric.

Legacy & Long-Term Impact

How this conflict shaped America and the world

The Yemen war's legacy is the definitive demonstration that the post-9/11 national security state operates beyond democratic control. Congress passed a War Powers Resolution to end involvement — the president vetoed it. Arms export laws prohibit transfers to countries that target civilians — the executive branch certified compliance despite overwhelming evidence to the contrary. The war has no congressional authorization, serves no vital national interest, and has created the worst humanitarian crisis on earth — yet it continues through four consecutive administrations of both parties. The war established that arms sales revenue and the Saudi relationship override human rights, international law, and congressional authority in American foreign policy. It created a template for war-by-proxy that insulates American policymakers from accountability: because no American troops are fighting, the war generates no domestic political cost despite killing hundreds of thousands. The humanitarian catastrophe — 377,000 dead, 85,000 children starved, the world's largest cholera epidemic — will define Yemen for a generation and stands as an indictment of the international order's inability to protect civilian populations from state violence enabled by great-power support. The Houthis' emergence as a regional military force, capable of disrupting global shipping in the Red Sea, demonstrates the strategic bankruptcy of the campaign: nearly a decade of bombing produced an enemy more capable and more hostile than the one that existed before the war began.

Lessons Learned

🗽

The Libertarian Perspective

Liberty, limited government, and the costs of war

America's most shameful ongoing war. US-made bombs dropped by US-supported Saudi jets on Yemeni school buses, hospitals, and weddings. 85,000 children starved to death. Congress voted to end it; the President vetoed. Both parties share the blame.

⚖️

Constitutional Limits

Executive war-making violates the Constitution and concentrates dangerous power in one person.

💰

Economic Impact

War spending diverts resources from productive uses, increases debt, and burdens future generations with costs they never agreed to pay.

🕊️

Human Cost

Every war involves the loss of human life and liberty. The question is always: was this truly necessary for defense?

"War is the health of the State. It automatically sets in motion throughout society those irresistible forces for uniformity, for passionate cooperation with the Government."
