How did the outcome of world war 2 contribute to the developement of the cold war

Russia and America always had their differences and Russia was a target of the Nazi's so while they were allies in WW2 they just shared a common goal and nothing else, after the war it was back to normal and the two dominant powers of the world where bumping heads

no one really purchased it themselves, it was all america, they had debates etc.

people had jobs and began to work. that’s why the commercial revolution was great.
