World War Two began in 1939 September 1 and had ended 1945 September 2. East Asia was in war prior to the beginning of WWII with Republic of China. The war had begun by the movement of Germany to invade Poland and when Germany Declared war on France and Great Britain. During this time America was in Alliance with 22 other countries, known as the Allis. Opposing the Allis, was the Axis. The Axis involved countries like Japan, the whole reasoning for the Manhattan Project, and Nazi Germany. Eventually after all the battling with Nazi Germany, in the winter of 45' the Russians had annihilated Nazi Germany and then to end the War, America had dropped Nuclear Bombs on Hiroshima and Nagasaki (Japan) which had ended the war. But in the dropping of those bombs, that was the only instance of nuclear bombing towards another country. But shortly after the war, America and Soviet Russia had entered what is now called 'The Cold War'. But this war was not like the wars Prior to this, it was Nuclear shoot out, like who would shoot first. Eventually no one did and the war was ended. But with the amount of nuclear power between the two countries was enough to blow the world to smithereens 14 times.
