The problem with not fighting back is that would probably increase the rate of theft of Palestinian land by the Israelis which, is as clear as day, premeditated and planned. They do not want a two-state solution because if they did, they would halt the siege and stop taking more land. But they do not do that. So therefore, you have to take their actions at face value, not their words, and put up resistance against these attacks on Palestinian land.
It's time to boycott Israeli companies and corporations that give them aid. Coca-cola is one of the biggest donators to Israel, which is illegal because any nation that has nuclear weapons cannot receive monetary aid. There are several other companies that do so as well, and they should be dealt with accordingly. Moreover, the staunch allies of Israel in Congress need to be voted out of office. This might be more difficult to do because everyone and their mother just loves Israel, but there are folks like Ron Paul who are against aiding them, so he's a start.
