Sustaining the Palestinian Authority past Annapolis

In addition to ending Abu Mazen's political career and easing a Hamas takeover, the Reut Institute warns that failure of the Annapolis Summit could contribute to the collapse of the PA and ultimately to an inversion of the international community's position towards the 'Two State Solution.'
Ha'aretz reports that Israel's Military Intelligence believes the failure of the Annapolis Summit could lead to Abu Mazen's resignation. Abu Mazen's resignation would create a lacuna in the Fatah leadership and ostensibly increase Hamas' influence.

In addition to ending Abu Mazen's political career and easing a Hamas takeover of the West Bank, the Reut Institute warns that failure of the Annapolis Summit could contribute to the collapse of the Palestinian Authority and ultimately to an inversion of the international community's position towards the 'Two State Solution.' (See: Failure of the Political Process: The Danger of Dissolution of the Palestinian Authority).

Therefore, sustaining the PA is a key Israeli interest which can be accomplished by strengthening it and the West Bank Fatah leadership prior to the conclusion of the current round of negotiations and independent of its outcome.

This could be achieved by transferring to the PA powers and authorities in the economic and diplomatic realms currently under Israel's control. In addition, Israel could consider freeing Marwan Barghouti in order to help prevent the expected vacuum in Fatah leadership in the case that Abu Mazen steps down.
