With the Marshall Plan never becoming a reality, would the Morgenthau plan (or a less extreme modified version) be put into place? Would Germany just be denied any aid and left in ruins? What would be the Soviet policy in the East?
Problem is, communist dictatorships and capitalist democracies tend to be diametrically opposed to one another. The only way to 'be friends' is for the Soviet communiststs to be overthrown and the country becomes a sort of democracy, or a communist revolution in USA turns that country into a dictatorship == or both countries 'find a third way' and become more like China (non-democratic but 'light handed' dictatorship with elements of both communism and capitalism) ...It is divided, but America and the USSR stay allies or at least don't actively oppose each other.
