The fighting and the Diaspora began soon after the non-binding General Assembly vote on the Parson Plan in 1947 as the Jewish Militia began clearing the Green Zone.

"The Plan was accepted by the
Jewish Agency for Palestine, despite its perceived limitations.

It was a non-binding resolution. It had no authority by itself to create any state, much less two. It should have gone back to the Security Council where it should have died. The former World Body, the League of Nations first proposed the Idea. I think it was the Peel Report or Commission that studied the Idea.

"It also noted that Jews at that time comprised only 10% of the population of Palestine."
