Economically- i would say booming because a lot of countries made tons of money from the war and had a ton at the end but countries like Germany, Russia, and France had cities that was totally destroyed and would take a lot of money to have them rebuilt.
Socially- i would say better than when the war was going on because at the end of the war people didn't have to be frightened, but a lot of people lost there homes in the war.
Politically- I would say great because treaties for nuke was established the united nations was up and running better and a lot of nations that was hostile lost there main source of power because they had to give some of it up.
