I thought not. In 1958 Egypt and Syria decided to unite and form a republic. The "union" lasted till 1961, when Syria decided to secede. Thedifferences between the two countries were greater than the similarities, and neither ruler wanted to give up any of his powers. Same thing with the Palestinians. I don't see the PLO and Hamas uniting for long. They will eventually separate again, or one will defeat and destroy the other..
