In West Bank, conditions 'not ripe' for Palestinian uprising
by Edmund Sanders

But in a not-so-subtle reminder that Israel can reseal the borders again, construction is underway on a new, expanded checkpoint. Meanwhile, Nablus residents -- from businessmen to teenagers -- say they are enjoying the broadest freedom of movement they have experienced in years.
Israel takes part of the credit for the apparent softening of Palestinian resistance through a carrot-and-stick approach under which it has eased checkpoints and permitted economic growth even as it has maintained an army presence and cracked down on militants.

"You have to have a very complex, nuanced approach of strengthening moderates, building the economy but not giving in to the terrorists," said Israeli Deputy Foreign Minister Danny Ayalon. "The [Israeli army] presence right now is not only necessary, it's diminished the chances of a third intifada."

Critics say Israel's strategy amounts to "beautifying" the occupation by relieving just enough pressure to weaken resistance and by making the West Bank dependent on billions of dollars in foreign aid.

"We are 'for sale' now," Kassem said, adding that some Palestinians today place a higher priority on jobs, education and lifestyle. "We are spoiled. People might get angry, but in a week they reach in their pockets and do nothing. We don't feel the occupation as much."

He noted that the Palestinian Authority, largely funded by the U.S. and other countries, now employs 180,000 people who "are not ready to sacrifice their jobs for another intifada."
