What would have happened if England and France had appeased Hitler longer prior to World War 2?
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.
