Well, it may seem a small differnce, but they didn't elect leaders who then turned to terror, they elected leaders who promised to continue already sufficiently demonstrated terror. They didn't elect them so they could build schools and community centres, they elected Hamas because Hamas promised to kill the pigs n' apes in Israel.
Sadly they wanted their cake and to eat it also, where are all their fellow Arabs? Why isn't the Arab world racing to aide the Palestinian People? Of course it's apparent that the Arab world uses the Palestinian people to spread their brand of Jewish Hatred but they have no interest in aiding the people of Palestine do they. Pawns of a barbaric culture, and I have no doubt the slaughter will continue in the name of their Prophet. They will of course blame Israel and the US, and the foolish will believe them.
