What are the factors hindering a peaceful resolution of the Israeli Palestinian conflict ?

There is one factor. It is the only and the ultimate factor that rules and dictates over who can go where, build where, and live where between the Jordan river, and the Mediterranean Sea.
I assure you, it is definitely not this factor below who can’t travel between one city and the next in the area he is supposed to rule, without the approval of the ultimate factor previously mentioned.
Go figure…
