You mean like when there were UN peacekeepers in southern Lebanon a few years ago to provide a buffer between Israel and Lebanon. And when Hezbollah attacked Israel, the peacekeepers sided with Hezbollah. Sounds like a great idea.
If Israel wanted the West Bank, they could take it. The UN is already highly anti Israel so the blowback would be nothing new.
Only some one like you would believe that Israel thinks encouraging terrorist attacks is a good thing. A few days ago, a 22 year old IDF soldier was killed by Hamas A couple of weeks ago, 3 female members of the IDF all under the age of 22 were murdered in a terrorist attack and a couple were murdered a few weeks earlier. Right, thats a good thing. And maybe you don't remember or never knew that on several occasions the IDF went into the West Bank and removed settlers that caused much violence from some of those WB settlements. Doesn't support your WB takeover does it.
All that you are doing is regurgitating old nonsense. BTW, why doesn't anyone complain that the border between Gaza and Egypt is blocked as well. Doesn't work into your mantra.
