It doesn’t work like that Sparky. Everything that DC decides to put troops in is not American by default. It’s not anti-Americanism to be against some of the crap of DC. Simply pointing to soldiers who were ordered to be there doesn’t make it the duty of an American to support that effort. It’s shameful to see the American military doing something on behalf of a government that is the home of Nazism in Europe.
Why the name calling?
As far as our GIs, they are not in a war, they are merely doing their routine American military duties, tell them they are wrong, and convince them to support the Russians by refusing to do their jobs.
Explain to them they are shameful or whatever you want to describe them as.
Perhaps you can expose to the world that a NAZI nation exists now and Russia must crush them to save the world from Nazism or whatever.
