I think, if one wishes to identify one single burning issue in the Arab/Israeli conflict, then that would be the settlements. This is a very difficult issue for the Israelis themselves, and my Israeli friends on this forum, may correct me if I'm wrong. The settlers are people who typically choose a place, even a parking lot, right in the inner city of a completely Palestinian township, in the heart of the West Bank, like Hebron, and decide that they will build a settlement right there, and live in it forever.The next thing you know is that the Israeli army moves in, surrounds the place with fences, squeezes the native Arabs out of the way, gives ample room to the settlers, and guarrantees their safety on a 24 hour a day basis. So you end up with some very fancy housings, with parks and schools and facilities, planted on native Arab land, surrounded by high fences, protected by one of the most powerful armies in the world, and connected to the main land by modern highways that only the settlers can use. Meanwhile, the native owners of the land, live in abject poverty, looking at the settlers through fences. If situations like the above do not inflame an otherwise perfectly containable situation, what does?And you talk to certain Israelis, and they look you straight in the eyes and they say "God gave us this land 3,500 years ago". If this is not insanity, what is? Then there comes the American President and his cabinet, and they mumble something about the settlements, but otherwise really don't do anything about the situation, and pledge complete and unwavering support for the state of Israel, and everyone feels so surprised that the Arabs feel angry, oppressed and betrayed.And when someone ties explosives around his body, and does something completely horrible, everyone is so surprised.
