America at war: Facts about WWI, WWII and Vietnam

America has been involved in a war for a total of 222 out of 229 years since 1776. That means since its founding, the nation has been at war 93% of the time. However, not all of those wars were ever declared one by an act of Congress, such as the Vietnam War.

Nonetheless, these wars and conflicts have had a long-lasting impact on the U.S. and countries around the world. We've scoured through lots of historical data to put together this list of facts you may not know or remember about American wars and conflicts, and how life changed in their aftermath.
