"Seeing a region swept by popular protests against leaders who couldn’t provide for their citizens’ basic needs, Hamas opted to give up official control of Gaza rather than risk being overthrown. Despite having won the last elections, in 2006, Hamas decided to transfer formal authority to the Palestinian leadership in Ramallah. That decision led to a reconciliation agreement between Hamas and the Palestine Liberation Organization, on terms set almost entirely by the P.L.O. chairman and Palestinian Authority president, Mahmoud Abbas.
Israel immediately sought to undermine the reconciliation agreement by preventing Hamas leaders and Gaza residents from obtaining the two most essential benefits of the deal: the payment of salaries to 43,000 civil servants who worked for the Hamas government and continue to administer Gaza under the new one, and the easing of the suffocating border closures imposed by Israel and Egypt that bar most Gazans’ passage to the outside world.
