One good reason for the establishment of a Palestinian state is that it will remove the plight of the Palestinians as a premise for Iran to go to war to annihilate Israel. Another good reason is that it is right and just and fair. The Palestinians got screwed when the UN established Israel. It is time to right that wrong. Preferably by the UN which created the problem in the first place.
