Can the Palestinian Authority control Gaza if Hamas is ousted?

AS ISRAELI TROOPS prepare to invade Gaza, one question keeps coming up: who should take control of it after they have rooted out Hamas—if, indeed, they are able to do so? Many, especially Israel’s allies, are looking to the Palestinian Authority (PA), which was thrown out of Gaza by Hamas almost two years after Israel withdrew its troops and dismantled its settlements there in 2005. But the PA seems to be in no position to take charge of the coastal enclave. In fact there are no guarantees that by the end of this war it will even be in control of Ramallah, the de facto capital city of the West Bank.
