Israel and Syria in the Golan Heights: U.S. Recognition of Israel's Sovereignty Claim [Updated March 26, 2019] [open pdf - 711KB]
From the Document: "On March 25, 2019, President Trump signed a proclamation stating that the United States recognizes the Golan Heights (hereinafter, the Golan) to be part of the State of Israel, based on the rationale that any future peace agreement should address threats Israel encounters from Syria-- including from Iran and the Iran-backed Lebanese group Hezbollah. The President did not specify the territorial bounds of Israeli sovereignty that the United States recognizes in the Golan. Israel gained control of the Golan from Syria during the 1967 Arab- Israeli war, and effectively annexed it unilaterally by applying Israeli law to the region in 1981 (see Figure 1 and textbox below for a map, synopsis, and timeline)."
