Thanks Keith, a good starting point but didn't a lot of other things happen before that point was reached. I know hindsight has 20/20 vision (maybe) but isn't that where we stand now? Isn't that the value of hindsight and historical analysis?

Wars don't start on Monday morning just after breakfast and the decision to start and continue a war in which millions of people died was what? All the powers that their were knew that millions were being slaughtered - why didn't they care enough to stop it?
