JERUSALEM — Israeli Prime Minister Benjamin Netanyahu has sparked a new diplomatic brushfire by declaring that the Golan Heights, seized from Syria in the 1967 Mideast war, is and should remain “under Israel’s sovereignty permanently.” But following tough international criticism, Israeli officials said Netanyahu’s statements had been misconstrued and that a 1981 decision to apply Israeli law to the strategic plateau fell short of annexation. The debate offers a window into a more nuanced Israeli perspective that, despite statements from the country’s hard-line political leadership, continues to leave the door open, just barely, to a peace deal when Syria’s civil war finally winds down. For now, the debate is largely academic.
