The "West Bank" is not, nor was it ever, "Palestinian" land. Under the principle of international law, uti possidetis juris, it is a part of Israel. Israel has been trying to relinquish it to the Arabs but has been rebuffed by their "leaders" every time it has made an offer. If the Arabs keep insisting that all of Israel is "Palestinian" land they will never have a state of their own in the "West Bank".
