Why This Site Exists

The Founders believed that a free people must understand what their government does in their name — especially when it comes to war. James Madison warned that “of all the enemies to public liberty, war is, perhaps, the most to be dreaded.”

WarCosts exists to make the costs of American military power visible, measurable, and undeniable. Not through opinion or ideology, but through data — sourced from the government's own reports, peer-reviewed academic research, and established investigative organizations.
