Obama is repeating Chamberlain's mistake regarding the Sudenland and Hitler.
Recall Hitler brought up phony land claims, muddied the situation long enough, incited violence among the ethic Germans and then Chamberlain got "peace in his time" by giving the land to Gemany.
It's the same nonsense here: this is not about land -- the arab claims to JUDEA and SUMERIA are weak both historically and recently -- the arabs only having obtained the land by killing the Jewish occupants priot/during WWII and, 20 years later, the Israelis getting (most) of their land back in 1967. (Leaving the "Jewish Quarter" of East Jersualem in the hands of the arabs, to give you an idea of how absurd the arab claim is.)
Anyway, the agenda of the arabs is not land, not peace, it's GENOCIDE.
The leader of Hamas said that today, that their goal of "ridding the world of Jewish vermin" was "one step closer today."
It's basic Jewish Genocide 101, and Haman, er, Obama, has taken the side of the killers.
