There is nothing like a sense of emergency and siege to unite the Israeli public behind his government. When the third intifada erupts, Netanyahu will be able to portray Israel’s war against it as a war against Iran and its satellites and neutralize criticism from the left about missed opportunities for peace in the past two years.From here on, the pressure will mount on Tzipi Livni to join an Israeli unity government to stand against the Palestinians and international community. When Mahmoud Abbas joins Hamas, Kadima cannot say it has a peace partner and cannot propose an alternative policy. Why should Kadima stay in opposition now?Foreign Minister Avigdor Lieberman grasped the situation first. He proposed to Netanyahu and Livni two weeks ago to work with him on an Israeli proposal for a final-status arrangement with the Palestinians.The reconciliation has also saved Netanyahu’s trip to Washington to speak at the AIPAC convention and in Congress. He no longer has to line the trip with concessions to the Palestinians. The pressure is off. He can make a Churchillian blood-sweat-and-tears speech, the kind he loves, and appear as the West’s last bastion of hope in the face of the Islamic wave washing over the Middle East.
