Jerry from Netherlands is right. If Israel kept Sinai instead of turning it over to Egyptian occupation, everyone would be better off.
Sinai would never have become a base for slavery, human traficking and unspeakable torture.
Sinai would not be a focal point of Jihad that threatens Saudi and American interests.
Israel would have strategic depth and energy independence, so would be safer.
Gaza would never have had free access to arms, Hamas would never have been able to be so powerful, there would have been peace.
A rational person would conclude that it is a world interest to give Sinai back to Israel.
Only a crazy person would suggest Israel withdrawal from Judea and Samaria.
