It was the most widespread war in history, with more than 100 million military personnel mobilised. In a state of "total war," the major participants placed their entire economic, industrial, and scientific capabilities at the service of the war effort, erasing the distinction between civilian and military resources. Marked by significant action against civilians, including the Holocaust , it was the deadliest conflict in history.
The war is generally accepted to have begun on 1 September 1939, with the invasion of Poland by Nazi Germany and subsequent declarations of war on Germany by France and most of the countries of the British Empire and Commonwealth. China and Japan were already at war by this date, whereas other countries that were not initially involved joined the war later in response to events such as the German invasion of the Soviet Union and the Japanese attacks on the U.S. Pacific Fleet at Pearl Harbor and on British overseas colonies, which triggered declarations of war on Japan by the United States, the British Commonwealth.
The war ended with the total victory of the Allies over Germany and Japan in 1945. World War II left the political alignment and social structure of the world significantly changed.
A quick personal thanks to those allies (excluding the french - complete wankers) who stood by britain while she faced the full conflict , for if britain had given up, germany (and the axis) would have likely won the war.
Victory at all costs, victory in spite of all terror, victory however long and hard the road may be; for without victory there is no survival.
-Winston Churchill during world war 2
America should have minded her own business and stayed out of the World War (world war 1). If you hadn't entered the war the Allies would have made peace with Germany in the Spring of 1917. Had we made peace then there would have been no collapse in Russia followed by Communism, no breakdown in Italy followed by Fascism, and Germany would not have signed the Versailles Treaty, which has enthroned Nazism in Germany. If America had stayed out of the war, all these 'isms' wouldn't today be sweeping the continent of Europe and breaking down parliamentary government — and if England had made peace early in 1917, it would have saved over one million British, French, American, and other lives.
