That's a good question. If I was a Palestinian who knew that I cannot militarily take over my enemy in the next 5-6 decades, and each of my attacks is retaliated by n times more damages from my side, I would have come to my sense and use peaceful means. Hamas is just destroying the Palestinian cause and does no good. Also, it is the responsibilities of Jordan and Egypt, as two countries involved in the issue from the beginning, to pressure both sides to implement Oslo treaty, and two states solution.
keeping islam away from politics, keeps islam clean from defaming its reputation due to some few extremists, and also makes muslims from different sects, to become united. Also, it makes non-muslims not to be ready to harshly react whenever they hear the word Islam.
