Interminable War Timeline
The U.S. at War


The U.S.—from its inception to the present—is plagued by perpetual, endless military adventures in its pursuit of global hegemony. Our "Interminable War Timeline" project shows just that, a history of U.S. armed supremacy and its excesses and destructive powers, both domestically and internationally, and the long-term consequences that follow its tragedies.
We want to help build a world that favors peace.

Below is a timeline of wars, which we here define as armed, violent conflicts, whether declared by Congress or not, in which the U.S. was involved in any capacity.
Of its 246 years of existence, the U.S. has had 14 years of peace.
