How would World War 2 have been different if Britain and France decided not to appease Hitler and Germany?

Answer 1

Can't know for sure, but I suspect he would have occupied all of Western Europe, including France. After a few years of building up an even larger military machine he would have tried for the Scandinavian countries. If the UK and France had not of acted in September 1939, Germany would have continued building and rearming its army. They would have fininsed construction of their aircraft carriers and war would have started in 1942. Russia probably would have been the target as that was Hitler's original objective.

Answer 2

It can only be speculation, of course. But forcing Germany to adhere to the terms of the Versailles Treaty might have meant the end of Hitler and the Nazis politically, returning Germany to less maniacal leadership, and forestalling if not completely preventing the European portion of WWII. Even if Hitler and the Nazis managed to stay in power through such a humiliating crisis of their own manufacturing, the onset of WWII would probably have been delayed at the least, and perhaps the forcible Anschluss with Austria, the shameful dismemberment of Czechoslovakia, the Non-Agression Pact with Stalin and the invasion of Poland might have been prevented. Millions might have grown old and died peacefully in their beds instead of finding an early grave. The British and French had missed chances, even before the Rhineland was remilitarized, to halt Hitler, as in 1935, when Germany began to rearm in excess of levels allowed in the Versailles Treaty, and started an Air Force, which the Treaty completely forbade. In 1936 these forces were nowhere near as formidable as they would prove to be in a few years, and could easily have been handled even if they fought, if dealt with resolutely.
