At the United Nations, Israel's Prime Minister Benjamin Netanyahu faced a dramatic scene. As he began his speech, dozens of Arab and Muslim nations walked out - joined by some African and European delegations. The U.S. and U.K. stayed - but only with junior officials. From the balcony though, some attendees clapped, even stood to applaud Netanyahu. In his speech Netanyahu vowed Israel "must finish the job" against Hamas. He blasted Western nations for recognizing Palestinian statehood, calling it a "disgraceful decision." But the walkout, the empty chairs, and the absence of top-level allies underscored one thing: Israel may be fighting Hamas militarily - but on the world stage, it is also fighting a diplomatic battle.
