This cuts both ways.
Both the US and Russia withdrew from that country in humialation.
In this case, let's imagine that the US eliminates all aid to Ukraine, which as a result is obliterated by Putin's hordes.
In that case, we look weak and pathetic in the eyes of the world AND Putin must somehow rule a devasted country that hates him while he flails to bring Russia into the modern world economically and technologically.
It's Afghanistan for both of us all over again.
Who wins?
CHINA!
