The original question postulates the Zionist movement aiming for Alaska, vs Palestine. However sucessfull or unsucessfull they are there, or any other alternatives leaves a more interesting side to the question, which has not ben raised here.

With no effort to create a Zionist or Isreali nation in Palestine how does the history of the Middle East and the Arab nations develop after 1945? How would the territory of Palestine be distributed politically? Would the adjacent nations fight over it?

Without the Isreali nation to hate will the adjacent Arab states waste the same ammount of their wealth on oversized armys?

With no Jewish nation in Palestine who will Arab demogogic politicians have to blame for their troubles?

With no Jewish nation in Palestine for the US to support how will its political relations with the Arab & Muslim nations be affected?
