John, maybe I'm wrong, but I think in the case of Fatah, there are two factors:

1) one of the reasons for Hamas' electoral success is that they were seen as far less corrupt than Fatah by the voters. Fatah has become more of something like a secondary policeman for Israel, and its members are probably content to get the money provided they are left to vegetate in peace. Hamas by contrast was seen as being at least more honest (which also makes me highly suspicious of attempts to portray Hamas as palestinians' own worst enemy rather than the nation that dropped tonnes of bombs and missiles on them)

2) A sense of hopeless despondency prevails in the West Bank. Palestinians - like the native Americans of long ago - see there is nothing they can do to stop the colonization and expropriation of their lands and homes by Israel and Israeli colonists. If they even try throwing rocks in frustration or anger they risk being shot dead in return, and colonists meanwhile are free to harass them however they wish with little or no recourse for the victims. So what you can't do anything about, you might as well accept, though that does not make it just.

But the key thing now is, where does the world go from here? How can this problem be resolved in a way to make as many people satisfied with the solution as possible, and in a fair and just way.
