Heh all this talk about WWII and the Cold War after i got done taking history lessons about it
, first of all all three contries needed help so each joined the an alliance, The three most import contries in the alliance were Russia,The United States, and Great Brit. The war was won blah blah then that led to the Cold War when The Big Three split germany into 4 sections(Yes four, since france was an allie in the war a chunk was givin to them) and the capitol of Germany was also split into 4, but there was a problem the capitol was in the USSR's section of Germany, later on this led to problems stalin started(like when he closed all main roads to berlin and american and brit transport can get food to civilians). Soon the arms race began both countries spent lots of money to create bigger and bigger bombs, but not a single fire was shot between russia,the united states, or russia all countries were affraid that if one sent a bomb then the other would and they would repeat until the world was completely destroyed. Eventualy durring the arms race(and the space race) the ussr ran out of funds to create weapons and the USSR collapsed. And about russians saying they didn't need us, is that why they joined the alliance? Most Americans I know would probley say we didn't need them, but I think we just needed eachother.
