The participation of the United States in World War II is often regarded as causing the Japanese to awaken "a giant sleeping" and is often considered an unbeatable superpower. In reality, the invincibility of the United States is not actually verified. Since the United States was separated from the rest of the western world by the sea on both sides of its boundary, only two attacks were made against the soil of the home country. It is not easy to test the invincibility of the United States but it is not easy to lose credibility, but whether Japan awoke Pearl Harbor on December 7, 1941 and awaken "a sleeping giant" There is room for discussion.
It should be a "war that ended all wars", but the Second World War began decades later. World War II began as a result of the desire for Germany and Japan to want more land. The total aftermath of this war eventually reached 2.5 million at that time, which was 2.5% of the world's population. It is impossible to say that the war of World War I is the end of all wars.
The end of all wars? I do not like this. Since it is the world's way to human life, conflicts will occur, war will happen and it will therefore be devastating. So why are you concerned about World War II? World War II brought about the formation of new powerful nuclear weapons, iron curtains and the subsequent Cold War, but it also did not allow any conflict to affect humanity as a whole again. In the new era of cooperation, lessons of war will still be applied and will become reality within the next few years. Because, as the monument of the Auschwitz concentration camp said, "It never comes".
The aftermath of the Second World War was the beginning of the era defined by the decline of all European colonial empires and the simultaneous appearance of two superpowers, the USSR and the United States of America. The allies during the Second World War, the US, the Soviet Union became competitors on the world stage and participated in the Cold War. Because it did not lead to a hot war publicly announced between the two countries. Western Europe and Japan were rebuilt by the American Marshall Plan, but Central and Eastern Europe belonged to the scope of the Soviet influence and eventually became "Iron Curtain." Europe is divided into a Western group headed by the United States and an East group led by the Soviet Union. Internationally, the alliance relationship between the two groups is gradually changing, and some countries are trying to avoid the Cold War through non-alliance movement.
