Is your point that the Arab world should all be one state? I think not. Thus your point I think is a red herring. There is absolutely no reason why the Palestinians should not have a seperate state if they want one with one caveat. That caveat is that they are deemed incorrigible, and there is no way to stop them from violating any treaty to which they agree, and relaunching their attacks on Israel; thus they need a babysitter. Of course if say Jordan becames the babysitter, the babysitter might be consumed, and then this no separate state thing would be all for naught in any event.
I think what is really going on here is some attempt to make Israel's desire for x% of the West Bank to seem less large by making it x% of the West Bank plus Jordan. I really don't seeing that getting much traction at all. Few will buy into that one.
My point, as you know, is that Jordan is "Palestine"

Is there any reason why Rastaferians should not have their own State? What about Trekies? Or "long suffering" constantly "humiliated" Chicago Cubs fans. Not to mention Kurds, Druze, Basques, many many others. All somewhat more distinguishable from their greater society then "Palestinians".
