Given that you are a cat why do you keep barking?Given there are plenty of Zionists who are unwilling to give up on Jewish supremacy in greater Israel in favor of peace and prosperity for all, it will stay ugly even if their Muslim neighbors do give up their dream of Islamic supremacy. Why? Because religious cultists of any stripe are intransigent nuts.
(In other words, you're asking us to take as a given something which is not true. It wouldn't be peace and prosperity, it would be death.)
