Leftist panty-waists are all twisted over the reference to the late 1930s and appeasement of Hitler, as though it’s way out of line. In reality, Hamas & Hizbullah & Iran’s leaders and their fellow jihad-scum are far MORE openly genocidal toward the Jews than was Hitler in the late 30s (he mostly had to disguise his intent and did not usually publicize the Holocaust for fear of arousing opposition). Sure, the jihadists do not now have the kind of forces that Hitler had, but their intentions are similar and the comparison with the inappropriateness of appeasement is quite on target.
Bush had every right, before the Israeli Knesset, to invoke the invalid doctrine of appeasement, since, it allowed the Holocaust to continue unabated and lead to the founding of Israel 60 years ago. It was a piece of history particularly apropos to the audience. That some take exception to that puts them in league with the perpetrators of the Holocaust.
