19 Wars Without Congress
The Founders gave Congress — and Congress alone — the power to take the nation to war. Over 248 years, that power has been systematically stolen by the executive branch. This is the story of democracy's most important failure.

📜 Article I, Section 8, Clause 11 — The War Powers Clause
“The Congress shall have Power... To declare War, grant Letters of Marque and Reprisal, and make Rules concerning Captures on Land and Water; To raise and support Armies, but no Appropriation of Money to that Use shall be for a longer Term than two Years; To provide and maintain a Navy; To make Rules for the Government and Regulation of the land and naval Forces; To provide for calling forth the Militia to execute the Laws of the Union, suppress Insurrections and repel Invasions.”
Read that carefully. Congress controls everything: declaring war, raising armies, funding them (with a two-year limit!), maintaining the navy, writing the rules for the military, and calling up the militia. The President's only military role, defined in Article II, is “Commander in Chief of the Army and Navy” — meaning he directs troops after Congress authorizes their use. The Founders were explicit. This wasn't ambiguous. It was deliberate.
What the Founders Intended — And Why
The men who wrote the Constitution had lived under a king who could drag his subjects into war on a whim. They had watched George III bleed the empire dry with foreign adventures. They were determined — obsessively determined — to prevent any American executive from wielding the same power. This wasn't a minor concern for them. It was the central question of executive authority.
The Constitutional Convention debated this at length. The original draft gave Congress the power to “make war.” Madison and Elbridge Gerry moved to change it to “declare war,” specifically to allow the President to repel sudden attacks without waiting for Congress — butnothing more. The change was narrow and intentional. The President could defend against an invasion. He could not launch one.
“The constitution supposes, what the History of all Governments demonstrates, that the Executive is the branch of power most interested in war, and most prone to it. It has accordingly with studied care vested the question of war to the Legislature.”
— James Madison, letter to Thomas Jefferson, April 2, 1798
Madison's reasoning was simple and devastating: executives like war. War expands their power, their prestige, their legacy. Kings started wars for glory. Parliaments resisted because they bore the costs. The same logic applied to presidents and Congress. Give the war power to the branch that pays the price, not the branch that reaps the glory.
“The President is to be commander-in-chief of the army and navy of the United States. In this respect his authority would be nominally the same with that of the king of Great Britain, but in substance much inferior to it. It would amount to nothing more than the supreme command and direction of the military and naval forces... while that of the British king extends to the declaring of war and to the raising and regulating of fleets and armies — all which, by the Constitution under consideration, would appertain to the legislature.”
— Alexander Hamilton, Federalist No. 69, 1788
This is Hamilton — the strongest advocate for executive power among the Founders. Even he was clear: the President commands troops in the field, but Congress alone authorizes their use. The President's role as Commander-in-Chief was, in Hamilton's words, “much inferior” to a king's military authority. He directs war once begun. He does not begin it.
George Mason put it most bluntly at the Convention: he was “against giving the power of war to the Executive, because not safely to be trusted with it.” Mason wanted it kept in the legislature because “he was for clogging rather than facilitating war.”
“Allow the President to invade a neighboring nation, whenever he shall deem it necessary to repel an invasion... and you allow him to make war at pleasure. Study to see if you can fix any limit to his power in this respect... Kings had always been involving and impoverishing their people in wars, pretending generally, if not always, that the good of the people was the object. This our Convention understood to be the most oppressive of all kingly oppressions; and they resolved to so frame the Constitution that no one man should hold the power of bringing this oppression upon us.”
— Abraham Lincoln, letter to William Herndon, February 15, 1848
Lincoln wrote this about President Polk's Mexican-American War — before Lincoln himself would stretch presidential war power during the Civil War. But his logic was sound: once you let the President decide when war is “necessary,” there is no limit. Every war becomes necessary. Every president finds a reason.
The Erosion: Step by Step
How 248 years of presidential overreach destroyed the Founders' vision.
1950: Korea — The Precedent That Changed Everything
President: Harry Truman (D)
When North Korea invaded South Korea on June 25, 1950, President Truman deployed 300,000 American troops without asking Congress for authorization. His excuse? It wasn't a “war” — it was a “police action” authorized by the United Nations.
This was constitutionally absurd. The UN Charter cannot override the US Constitution. The Founders didn't say “Congress shall have the power to declare war unless the United Nations says otherwise.” But Congress let it stand. Senator Robert Taft was nearly alone in protesting:
“The President is usurping his powers as Commander in Chief. There is no authority to use armed forces in support of the United Nations in the absence of some previous action by Congress dealing with the subject.”
— Senator Robert Taft (R-OH), 1950
The result: 36,574 Americans dead. A three-year war with no congressional vote. And a precedent: if you call it something other than “war,” you don't need Congress. Every president since has exploited this loophole.
1964: Gulf of Tonkin — The Blank Check Built on Lies
President: Lyndon Johnson (D)
On August 2, 1964, the USS Maddox was allegedly attacked by North Vietnamese torpedo boats in the Gulf of Tonkin. Two days later, a second attack was reported. President Johnson asked Congress for authorization to respond.
The Gulf of Tonkin Resolution passed 88-2 in the Senate and 416-0 in the House. It authorized the President to take “all necessary measures to repel any armed attack against the forces of the United States and to prevent further aggression.” Johnson used it to escalate from 23,000 advisors to 536,000 combat troops.
The problem? The second attack — the one that triggered the vote — almost certainly never happened. Declassified NSA documents revealed in 2005 that intelligence was deliberately manipulated. Secretary of Defense Robert McNamara later admitted doubt about the second incident. The entire Vietnam War — 58,220 Americans dead, 2 million Vietnamese civilians killed — was authorized based on fabricated evidence.
“For all I know, our Navy was shooting at whales out there.”
— President Lyndon Johnson, privately, 1965
Only two senators voted no: Wayne Morse of Oregon and Ernest Gruening of Alaska. Morse prophetically warned: “I believe that history will record that we have made a great mistake in subverting and circumventing the Constitution.” He was defeated in the next election. He was also right.
1973: War Powers Resolution — The Failed Fix
Passed over President Nixon's veto
After the Vietnam disaster, Congress tried to reclaim its war power. The War Powers Resolution of 1973, passed over Nixon's veto, requires the President to:
- Consult with Congress before introducing forces into hostilities
- Notify Congress within 48 hours of committing armed forces
- Withdraw forces within 60 days (with a 30-day extension) unless Congress authorizes continued action
- Remove forces at any time if Congress passes a concurrent resolution
In theory, this should have worked. In practice, it has been a dead letter from day one. Nixon called it “both unconstitutional and dangerous.” Every subsequent president has agreed — while simultaneously violating it. The scorecard:
- Ford: Evacuated Saigon, Mayaguez incident — no congressional authorization
- Carter: Iran hostage rescue — no notification until after the fact
- Reagan: Lebanon, Grenada, Libya, Iran-Contra — all bypassed Congress
- Bush Sr.: Did seek authorization for Gulf War (barely passed 52-47)
- Clinton: Bosnia, Kosovo, Haiti — all without authorization. Kosovo bombing lasted 78 days, well past the 60-day limit
- Bush Jr.: Got AUMFs for Afghanistan and Iraq but stretched them far beyond their intent
- Obama: Libya bombing campaign — didn't even claim AUMF authority, said it wasn't “hostilities”
- Trump: Assassinated Iranian General Soleimani — notified Congress after the fact with a classified memo
- Biden: Airstrikes in Syria — notified Congress after they happened
No president has ever been held accountable for violating the War Powers Resolution. Not once in 53 years. Congress has never enforced its own law. The resolution is a constitutional corpse — passed with good intentions, dead on arrival.
2001: The AUMF — 60 Words That Authorized Endless War
President: George W. Bush (R)
The Authorization for Use of Military Force — S.J.Res.23
“That the President is authorized to use all necessary and appropriate force against those nations, organizations, or persons he determines planned, authorized, committed, or aided the terrorist attacks that occurred on September 11, 2001, or harbored such organizations or persons, in order to prevent any future acts of international terrorism against the United States by such nations, organizations or persons.”
60 words. No geographic limitation. No expiration date. No requirement to return to Congress. Passed September 14, 2001 — three days after 9/11. Vote: 98-0 Senate, 420-1 House.
Congress was in shock. The towers had fallen three days before. Anthrax letters were arriving at congressional offices. Members were afraid — and under immense political pressure. Voting “no” on anything that looked like fighting terrorism was career suicide.
Only one person saw clearly through the fog of grief and fear.
The Lone “No” Vote: Barbara Lee
“However difficult this vote may be, some of us must urge the use of restraint. Our country is in a state of mourning. Some of us must say, let's step back for a moment. Let's just pause for a minute and think through the implications of our actions today so that this does not spiral out of control... As we act, let us not become the evil that we deplore.”
— Rep. Barbara Lee (D-CA), September 14, 2001
For her vote, Lee received death threats. She required a bodyguard for months. Talk radio called her a traitor. The Wall Street Journal editorial board called her vote “the most irresponsible act in Congress since the last congressman voted against World War II.”
She was quoting a clergy member who had spoken at a memorial service that morning: “As we act, let us not become the evil that we deplore.” She warned that the AUMF was a blank check. She predicted it would be used to justify wars far beyond its original intent.
Twenty-five years later, she has been proven right on every count. The AUMF has been used to justify military operations in at least 22 countries, against groups that didn't exist on 9/11, in places that had no connection to the attacks. It is the most consequential single vote in modern American history.
22+ Countries Under the 2001 AUMF
The AUMF authorized force against those who “planned, authorized, committed, or aided” the 9/11 attacks. Here are some of the countries where it's been invoked:
Most of these countries had no connection to 9/11. Many of the groups targeted — ISIS, al-Shabaab, Boko Haram, Houthi rebels — didn't exist in 2001. The AUMF has been used against enemies of al-Qaeda, affiliates of affiliates, and organizations that are explicitly at war with al-Qaeda. The legal fiction is staggering.
2002: Iraq AUMF — The Second Blank Check, Built on WMD Lies
President: George W. Bush (R)
Not satisfied with the 2001 AUMF alone, the Bush administration sought a separate authorization for Iraq. Secretary of State Colin Powell presented “evidence” of Iraqi weapons of mass destruction to the UN Security Council on February 5, 2003 — satellite photos, intercepted communications, drawings of mobile biological weapons labs.
None of it was true. The WMDs didn't exist. The aluminum tubes weren't for centrifuges. The mobile labs weren't weapons labs. The intelligence was cherry-picked, manipulated, and in some cases fabricated. The primary source — codenamed “Curveball” — was later revealed to be a fabricator whom German intelligence had warned was unreliable.
“It was all wrong. The intelligence community was dead wrong.”
— The Robb-Silberman Commission on WMD Intelligence, 2005
Congress voted 77-23 in the Senate and 296-133 in the House to authorize the Iraq War. Among those voting yes: Hillary Clinton, Joe Biden, John Kerry, and Chuck Schumer. The result: 4,599 Americans dead. Over 300,000 Iraqi civilians killed. Cost: $2 trillion and counting. All based on lies.
2011: Libya — Not Even an AUMF
President: Barack Obama (D)
In March 2011, Obama ordered US military forces to participate in NATO bombing of Libya without seeking any congressional authorization at all. When the bombing exceeded the War Powers Resolution's 60-day limit, the administration argued — with a straight face — that dropping bombs from aircraft didn't constitute “hostilities.”
“US operations do not involve sustained fighting or active exchanges of fire with hostile forces, nor do they involve US ground troops.”
— Obama administration legal rationale for Libya, 2011
By this logic, the President could bomb any country indefinitely without congressional authorization — as long as he used aircraft instead of ground troops. Obama's own Office of Legal Counsel disagreed with this interpretation. He overruled them. Libya descended into a failed state that remains unstable today.
2020: Soleimani — Assassination Without Authorization
President: Donald Trump (R)
On January 3, 2020, a US drone strike killed Iranian Major General Qasem Soleimani at Baghdad International Airport. This was the assassination of a senior government official of a sovereign nation — an act of war by any historical definition. Congress was not consulted beforehand.
Trump notified Congress after the strike with a classified memo. The administration initially cited the 2002 Iraq AUMF as justification — an authorization passed to address Saddam Hussein's alleged WMDs, now used to justify killing an Iranian general 18 years later. Later they shifted to claiming inherent Article II self-defense authority.
The strike brought the US to the brink of war with Iran. Iran retaliated by firing ballistic missiles at US bases in Iraq, causing traumatic brain injuries in over 100 US service members — injuries Trump initially dismissed as “headaches.”
2026: Iran — The Pattern Continues
President: Donald Trump (R)
As of early 2026, the United States is engaged in escalating military operations against Iran without any new congressional authorization. The administration has cited the 2001 AUMF, the 2002 Iraq AUMF, and Article II self-defense authority — the same legal justifications used for every unauthorized military action since 2001.
The Founders' nightmare has been fully realized. The President of the United States can wage war against any country, at any time, for any reason, without a congressional vote. The constitutional requirement that Congress authorize military force has been reduced to a polite fiction that everyone acknowledges and no one enforces.
The Imperial Presidency
Historian Arthur Schlesinger Jr. coined the term “the imperial presidency” in 1973 to describe the accumulation of war powers by the executive branch. He argued that presidents had gradually transformed themselves from constitutional officers into elected monarchs — particularly in the realm of foreign policy and war.
Every president's excuse follows the same pattern: the situation is urgent, the threat is imminent, there's no time for debate, the President must act. But the Founders anticipated this argument. They knew that every executive would claim urgency. That's precisely why they gave the war power to a large, deliberative body that couldn'tact quickly. The friction was the point. The delay was the safeguard.
The result of destroying that safeguard? Korea. Vietnam. Iraq. Afghanistan. Libya. Syria. Yemen. Somalia. And now Iran. Trillions of dollars. Millions of lives. Zero declarations of war.
What the Founders Would Say
If James Madison could see the current state of presidential war powers, he would recognize exactly what he warned against. The executive branch has claimed — and Congress has surrendered — the very power the Constitution was designed to prevent any single person from holding.
The Founders didn't give Congress the war power because they thought Congress was wise. They gave it to Congress because they knew the President was dangerous. Not any particular president — every president. The office itself, with its concentration of power and its incentive for glory, was inherently prone to war. Only the friction of democratic deliberation could check it.
That check no longer exists. Congress has voluntarily abdicated its most solemn responsibility — the power to decide whether American soldiers live or die, whether American treasure is spent on war or on its citizens. Most members prefer it this way. Voting for war is politically risky. It's easier to let the President act and then criticize the results.
The Founders would not merely be disappointed. They would recognize that the republic they built has failed in the very way they most feared.
