How many people have died in wars the United States has prosecuted since WW2? It difficult to count. War kills people in many ways. They die directly in combat or as civilian deaths due to military action, or they may have died of more indirect causes. Its a complicated picture that requires lengthy study. Many scholars and institution have performed much research to find answers to the question. A low estimate is somewhat above one million for the Vietnam War. The Vietnamese government puts the number around 3,000,000. In the Korean war estimates run up close to a million with wide variation between sources from the US Defense Dept. to the Chinese. Countercurrents.org puts the total number of deaths from American wars after WW2 at 10,000,000 or higher. This figure includes deaths in Cambodia and Laos during the Vietnam era. Proxy wars like those in Angola, Congo, East Timor, Sudan and others have huge additional casualties perhaps totaling higher than 10,000,000.
here is one website dealing with the question:
Injury, property damage, loss of infrastructure, loss of natural habitat, and the psychological toll on the "victors," victims, survivors, is beyond reckoning. To say nothing can be done is like saying there will always be slavery, or there is nothing you can do about climate change.
Why talk about it? Because so many have no idea of the scale of US war making.
