After 52 years it is time for the United States to fully recognize Israel's Sovereignty over the Golan Heights, which is of critical strategic and security importance to the State of Israel and Regional Stability!
The Heights are Syrian lands that were occupied by Israel during its 1967 war of aggression against Egypt and Syria.
