Teribus: " Israeli's said, "You want your land back, you openly and officially recognise our right of existence and respect our sovereignty." Some countries did (Egypt and Jordan) Syria did not. Within the area of Palestine certain groups did not accept and groups such as the PLO, Fatah and latterly Hamas and Hezbollah sprung up backed by Gadafi in Libya, Saddam Hussein in Iraq and by Iran"

But if Jordan has recognised Israel's 'right to exist' and Israel grabbed the West Bank during the 1967 war, and has promised to hand back / vacate land grabbed in return for peace and recognition, why didn't it simply withdraw from the West Bank (which wasn't part of the original mandated state of Israel in the first place) and there would have been no PLO / Hamas etc.,?
