The United States is not at war. The United States hasn't been at war since the Japanese signed a surrender document in 1945.
Only Congress can declare war. They haven't done so since December 8, 1941.
Korea was a Police Action. Vietnam was a Conflict. Gulf I was something, but not a war. Gulf II isn't a war either. Nor were Lebanon, Somalia, Bosnia, and the rest.
So all those who died in those places couldn't be war dead.
