The Russians did most of the heavy-lifting taking care of the German Nazis during WWII, looks like they’ll have to do it again, except this time the West is for the Nazis.
Whom are you calling NAZIS?
They did most of the heavy lifting not out of choice but because they were literally fighting for their lives in a way the US was not. Germany was pushing deep into Russia and running away was not an option for the Russian people. If Hitler had conquered Russia, he would have liquidated them.
Note that Russia made WWII possible via the Molotov-Ribbentrop Pact. Without a secure eastern front, would Germany have invaded the West? Ultimately, apart from Germany, the country most responsible for WWII was Russia. That they took the most casualties of the Allies wasn't just deserved - it was perhaps better than they deserved.
