Guys, wars always start because of many causes. We once had a discussion about WWI and who started it. It was actually not as simple as everyone believes. So is the same with WW2. You could blame anyone if you want, America for not being stronger and more forceful before anything went out of hand (actually blaming them for being isolationists), GB and France for not stopping Hitler earlier and, declaring war on Germany (both thing are in contradiction, did you notice?). All three of them for Versailles... Russia for making a pact with the aggressor, and of course Hitler and Germany for being so aggressive in the first place. But what's the point? Mistakes are made, war starts, it's sad but true. Happens all the time and still today. Usually if you dig far enough you find that both parties share the blame, some more than the other but both none the same.
