while I support a peace with Egypt and would also support significant joint development and trading progress in a number of ways beneficial to Egypt,
giving Sinai to Egypt will prove to have been a most serious mistake ... as it nearly did just a couple years ago when Obama enabled the overthrow of the Egyptian government by his Muslim Brotherhood terrorist gangster mass-mudering IslamoNazi buddies. A Cairo government in their hands would guarantee another war on Israel (a war in which Egypt would have to be destroyed outright, alas)....
You must have meant to say giving the west bank to egypt.
Israel gave Egypt the Sinai to Egypt after the six day war.
Israel was given Gaza because Egypt wanted to get rid of that hell hole and insisted Israel take it.
