Hamas may be a terrorist group, but for decades, Israel and the wider world have treated it as a fact of life. John Kerry visited the group as a senator, prior to becoming secretary of state. So, too, did many European officials. The Turkish parliament gave Hamas leader Khaled Meshal a rousing ovation during his 2006 visit to Ankara. Today, Qatar competes with Turkey to shower funds and support on the group whose charter calls for the extermination of Jews.
