It's like the Germans in the 1930s -- I was discussing this with my wife and one reason the Germans were so eager to start war again in 38 was because they did not experience fighting on their own territory -- the French and Belgians did and were reluctant to see this happen again. The Germans didn't and got that "stab-in-the-back" myth. Just imagine if the Entente had fought into Germany and showed the people what hell is like? there would have been no shitler, no holocaust, no pojramos.
The German people were nowhere near as bellicose as Hitler and the Nazis. For Hitler, the Great War was the highlight of his life, his minor success reverse his previous life long failures.
In his book, Inside the Third Reich, Albert Speer says that after the fall of France, the mood of the German people was subdued, much to the disappointment of the Nazi Party. Most Germans did not welcome the War. After World War 2.0, the Germans did experience war like few other people ever had and had no taste for it.
When people like Farrakhan call for a War on white people (and he means an actual shooting war) I think the only people who would welcome such are war are people who have absolutely no idea what war is.
The Allies certainly weren't going to make that mistake the second time around.
