The question is whether it was a strategic move to withdraw from Gaza or a humanitarian one. I would guess the former.

From my reading, it seems that Israel won't really buck and if the government was to do so, their parliament would prevent such a move eventually by electing another. Let's face it, there are extremists on both sides. In fact, the Israeli (government) will not even let Palestinian refugees to return to their homes because "they would out number us poor Jews and destroy our notion of Jewish state". Well, go figure, drive them off their land and then say they cannot come back because then the occupiers wouldn't be the absolute majority anymore.

Going further, I wonder what would have happened if nations hadn't gone gung-ho blocking Palestine off, cutting aid and supplies after they democratically and in a non-rigged election voted Hamas into power. I imagine if the freedom-loving Western nations had stood by them regardless of their differences, there could be prospects for peace, but unfortunately there are lobbies and certain loud voices that would have caused some to not be re-elected, eh?
