The big problem, as I see it, is that the Palestinian people were stupid enough to elect Hamas to government. Up to this point the people could distance themselves from the actions of a terrorist organisation, being nothing more than innocent victims of circumstance however, when they elected them to government the effectively said that this is the future they want. Seriously, they were much better off with the old PLO, no matter how embroiled in strife they were, they ceased official hostilities when they gained political legitimacy in 1993, Hamas have not done so and have therefore never been recognised internationally and as such continue to bring the rain down on their people. Not that this excuses Israel in any way shape or form but when you are first stuck in a cave with an angry bear the last thing you should do is start poking it with a stick.
