In November 2010, the U.S. government offered Israel a package of incentives in exchange for an agreement by the Israeli government to a 90-day freeze on settlement construction in the West Bank excluding East Jerusalem. The centerpiece of the deal was a military aid package worth $3 billion, including delivery of 20 additional F-35s,various missile and layered defense systems, and an explicit acceptance of the legitimacy of existing security needs and a commitment not to redefine them.[85] In addition to security provisions, the proposed incentive package also included a U.S. promise to veto any U.N. Security Council resolution relating to the peace process during the agreed upon negotiating period and a guarantee that the U.S. would not ask Israel to extend the 90-day moratorium when it expired.[86] The Security Cabinet of Israel considered the offer.[87] Former Ambassador Dan Kurtzer, commenting on the deal said: "But now, the administration says it is prepared to pay off Israel to freeze only some of its settlement activity, and only temporarily. For the first time in memory, the United States is poised to reward Israel for its bad behavior."[88] Palestinian President Mahmoud Abbas rejected the U.S. freeze proposal, as it did not include East Jerusalem, while Chief Negotiator Saeb Erekat reiterated demands for unconditional recognition of the 1967 borders, and for withdrawal from all of East Jerusalem.[89]
