@GOKOR:

With respect to your grandfathers and the several other "old people", saying that the entirety of the German army wasn't Nazi during the rule of the Nazi party is misleading. After the rearmament of German forces, Wehrmacht pretty much was all Nazi after Hitler took dictatorship. This is basic high school history.

If there were some who didn't agree with Nazi ideals and the policies in place, then sure - I'd grant that they weren't Nazis. However, undoubtedly - for the most part - the entire German Wehrmacht under Hitler was unquestionably a Nazi force.

I'm sure the US has quite a few men and women serving in their armed forces who have opposing political views than the government they serve. This does not make the US military any less a democratic republic.
