Because the formation of Israel has split up Palestine into numerous peices, and the Israelis are still occupying Palestine. Although it pulled out of Gaza, the West Bank was still under a harsh Israeli military occupation. And now of coarse the Israelis are moving back into Gaza. In occupied territories we see Israeli government-sponsered settlers; which directly and literally constitutes imperialism and colonialism. Perhaps Palestine would be given a chance if it weren't being occupied and under harsh conditions, and perhaps if it weren't for Israeli war crimes. But a lot of people like to forget the fact that Israel is occupying Palestine, and virtually all of the quote "terrorist" Palestinians are fighting for their independence, freedom, and homeland (although there are radical islamic sects).
