The US did not plan on fighting a hundred Iwo Jimas and what happens when Putin wins? Ethnic cleansing and a long brutal guerilla war. It is Russia that cannot win and Russia that has already suffered strategic defeat by bringing Sweden and Finland into NATO and convincing Poland to massively rearm and the Germans that they too must prepare for war. You cannot afford this victory. You have already squandered the tawdry military legacy of 70 years of totalitarian rule and will never be able to rebuild what you had when the war broke out.
Glad to see you have it all figured out...
