I think your position fails logically. Almost as many Palestinians, excluding fedayeen, live in Jordan as live elsewhere. And the West Bank WAS part of Jordan from '48-'67.
While there are ruling families/tribes, and jealousies between others, there exists no one tribe - one country rule in the Arab world.
You've neglected to mention Black September.
And the West Bank WAS part of Jordan from '48-'67.
It was also part of the Ottoman Empire c.1550 to 1918, and of the British protectorate 1920 to 1948. So what?
While there are ruling families/tribes, and jealousies between others, there exists no one tribe - one country rule in the Arab world.
I was speaking broadly. Evidence suggests that the Sunni-Shiite animosity is worsening, that tensions between Arab and non-Arab Muslims are worsening, that Lebanon is coming apart again, that Egypt and Iran are in for some very rough times. And, of course, Iraq is in the midst of a combined civil war and occupation.
