Israel/Palestine

What Israel " gave up" as you call it was an occupation, not sovereignty. As well it should have. International law and the UN Charter ban acquiring territory through war. Not that that matters to Israel, with its history of annexation and now hell- bent on annexing at least the West Bank.

Israel was never willing to give up the West Bank. Surely you are not referring to the
1987 attempt by Israeli foreign affairs minister Shimon Peres and King Hussein to SECRETLY arrange a peace agreement in which Israel would concede the West Bank to Jordan. Peres had no authority to sign such an agreement, had no political or popular support for it and of course it was rejected by Israeli PM Shamir.

But contrary to what you claim, Jordan did indeed want the West Bank.
