We found what the results of national isolationists' views are - in 1930s-1940s. There is a difference between somewhat isolationist policies (which I would support, sometimes) and not supporting resistance to blatant military expansionist aggression in the middle of Europe.
Some people are just incapable of learning from the past. We have been dragged into World Wars by Europe... twice. Let them sort out their own problems. We have problems of our own at home. Russia has the GDP of New Jersey so the EU should be able to handle it. By the way... if you are going to invoke Hitler you might want to avail yourself of some knowledge... like the difference between the Nazis and the Communists. You've got your polarization all wrong and it makes you look somewhat foolish. But evidently millennials don't read and develop their geopolitical ideas from Facebook.
imagine thinking modern Russia is communist and trying to lecture someone on geopolitics or history? This is peak Dunning Kruger
I am not a "millenial" and I was born and grew up in the Soviet Union so I think I know Russia a bit better than you. And the regime in Russia right now is purely authoritarian/faschist, not at all "Communist" (not that that's much better).
Maybe move to Russia? They have a better life than the Germans according to Russian propaganda. Putin's children live outside Russia. Lavrov's children live outside Russia, the children of the President of the Russian National bank live in Scandinavia. Almost all oligarchs live outside of Russia... Because it is so good in Russia!
When your hypothetical sons are drafted and end up KIA on some foreign battlefield that has literally nothing to do with the vital interests of the United States I wonder if you will still be so glib.
So you are consumed with hatred towards your Rodina to the extreme detriment of your adopted country. We could do without your type.
