That part supporters of either group fail at is that neither Hamas or the Israeli government are worthy of support or in the right. One behaves worse than the other at the moment. But there can never be peace with those two in power. It's a really fucked situation and my heart really hurts for the people caught in the crossfire of it all.
It seems that netanyahu bolstered hamas for years for political gain, and squashing any moderate palestinian activists, teachers or politicians. Like jailing them. What happened was really predictable.
And both of them are getting what they want, to be the kings of ashes.
