What is the motive?
What is the benefit?
From U.S. perspective?
The way to achieve peace in Palestine is let one side wipe out the other, or push both into the sea.
Since this isn't being advocated, no one is serious about solving the problem.
The original Palestinian refugee population of 700,000 expelled during the war and 300,000 that fled before it, should have been resettled in other countries.
1 million people can fit in the Capital Mall. They should have resettled in neighboring countries and taken their lumps.
The Ottoman empire exterminated 1.5 million Armenians and that gets little press today. Saddam exterminated about 400,000 Shiites.
I guess the lesson is Israel should have exterminated Palestinians instead of letting them run away.
Something else that isn't noted, is many if not most of the displaced Palestinians were recent immigrants attracted to the economic growth after the Jews moved in.
