It appears that there was a deal to open the borders to Gaza. It seems to have involved a prisoner release by Israel and the PA in exchange for the release of Gilad Shalit, but PA walked away from the deal, “because the Fatah officials believed it would weaken them.”
These guys really don’t have a clue. If Hamas releases Shalit, is ready to release Shalit, even with a significant release by the Israelis is going to be a net minus for Hamas, because it removes a bargaining chip from their hand, and because it means that they have negotiated a deal.
But the leadership of the PA is so damn timid, they snatch defeat from the jaws of victory.
