Mubarak is 82 and Abbas 75. Neither will live forever and the situation in Gaza will change in their absence. How it will change is open to interpretation. One thing there is likely certain. Hamas will never recognize Israel's "right" to exist without agreement on the Palestinian "Right of Return." Hamas, if anything, has proven its resiliency. What action will Israel take? I would guess none as Israel will only accept peace on its terms.
