The thing is, it would be great to see peace in the Middle East. But there is two things
One) Would the Arabs really stop attacking Israel??
Two) Why should Israel give up something when all that the Arabs are doing is killing innocent civilians in terrorist activities. If Puerto Rico kept bombing Florida enough, would we give them their independance? (not an exact parallel but kinda close)
Three) If a lone bomber does something, will Israel just go back and retake the lands? Will it just be a cycle?
I added a third but that wasn't in my inital thought.
