Dear lord did people think millions of Americans died? Guess what? No war in the history of our country has killed even 1 million Americans. The most costly war in terms of lives was the Civil War, and even that didn't reach 1 million.
We got lucky, places like the Soviet Union lost millions upon millions of soldiers and millions of civilians too. That is kind of why the Soviet Union had some ill feelings towards us. They felt we basically sacrificed them. I think their total losses totaled over 20 million including civilians.
