I don't like terrorism, either. But, that's all they've got. More importantly, the government of Palestine has worked to eliminate terrorism. The direction that Abbas has taken is one of insisting that negotiation is the ONLY legitimate approach. Therefore, he has cooperated with Israeli security forces in reducing terrorism and has applied to the UN and other institutions that show some likelihood of moving the situation toward peaceful resolution. His unity government required negotiation to be the ONLY direction, and he got Hamas to sign that and become minority members of his unity government. The unity government would have taken over important Hamas revenue streams such as the fees for border crossings and the unity government would become responsible for the aid and other programs that Gaza has in order to help civilians. That would have been a crushing blow to Hamas, as Hamas would no longer be well funded and would not be the entity working on the betterment of the people. Of course, Israel HATED that direction, and killed it.
