They're having some trouble with this part of your thought. Perhaps more bombs will show them the way... :)
Yes, they've had trouble with this part. I'd prefer they had the intelligence, decent leadership and the other Arab nations to show them the way. They almost made it in Jordan, but Arafat blew it.
they're attached to their homeland and will fight for it until they feel there's no hope.
That's pretty damning of these people. Makes them out to be anachronistic un-changing suicidal fools. While the other Arabs treat them as useful idiot cannon fodder.
They were attached to Jordan for a while, they can become attached to a new home without the destruction of Israel - if all the radical terrorists, governments included, in the region weren't blowing up every chance they get.
The problem is far from being all the displaced people attached to their homeland as usual. If it were, you'd have Jewish refugee camps bombing Arab states that kicked them out sixty years ago.
Your opinion of these folks is much lower than most.
