I don't know why you believe that a decades-long strict dictatorship like Russia has more democratic support for its "evil" government than a country whose leader was elected just 1 year ago with approximately 50% of the vote.
And also, our whole military recruitment strategy here outside of drafts has been "the GI bill" – paid tuition in exchange for lining up to go to war.
I don't know that the gap in morals is as wide as you think.
Which historically has worked more for us, than against us.
Russians are much, much worse than Americans in terms of their eagerness to kill others, in my opinion. I wish it were not so.
