There is a strong case for saying that Palestine is a lost cause. And it, the case, can be summarised as follows.
* The nuclear-armed Zionist (not Jewish) state of Israel is the regional superpower and not remotely interested in peace on terms the Palestinians could accept. The vast majority of its Jews have been brainwashed by Zionist propaganda and as a consequence are not open to rational and reasoned discussion about justice for the Palestinians. And that leaves Israel’s leaders free to continue the policy of taking (stealing) for keeps the maximum amount of Palestinian land with the minimum number of Arabs on it.
* As things are the major world powers are not going to use the leverage they have to cause (or try to cause) Israel to end its defiance of international law and denial of justice for the Palestinians.
