The US military would with enthusiasm, have bombed Ukraine into rubble. The Russians do not think that way. Winter on the steppes is nothing to play with and some infrastructure has to be left intact…

One thing that will happen is the able bodied will become super valuable…

For basics like carrying water, scrounging for food,  firewood and or even make their own coffee. The effete, spoiled and or worthless and the glorified obese will face major mental attitude and immediate massive physical adjustment…

I am not sure that even 75% of the Western population could even adjust to the basic existance coming their way?

Immigrant populations who remember what work is?

Will be favored…
