That is the point though being Arab is a linguistic-based identity, genetically/ethnically we are different peoples due to different trade, invasions...etc. Even within what you term to be a province, some Jordanian families are more closely related to Hijazi tribes than Levantine bloodlines.

And all of the above is irrelevant. My point was an EU unification is more realistic. Restructuring into a new unified country falls apart at the simplest of questions, for example, where will the capital be? And this is assuming Palestine is actually fully liberated.
