premise: Israeli Prime Minister Benjamin Netanyahu apologized on Friday to Turkish Prime Minister Recep Tayyip Erdogan for a raid on a Turkish flotilla ship, a move that will help restore strained ties between the countries.
  The call, which happened as President Barack Obama wrapped up his first presidential visit to Israel, was an unexpected outcome from a Mideast trip that seemed to yield few concrete steps.
  Mr. Netanyahu's office confirmed that the Israeli leader, in a conversation with Mr. Erdogan, "agreed to restore normalization between Israel and Turkey, including the dispatch of ambassadors and the cancellation of legal steps against [Israeli Defense Forces] soldiers." Mr. Erdogan accepted the Israeli apology, the prime minister's office said.
  Mr. Erdogan has long sought an apology for the raid in May 2010 on the Mavi Marmara, which was part of a flotilla that sought to break Israel's blockade of Gaza. An Israeli raid on the ship left nine passengers dead, all of them Turkish or of Turkish descent.
