In the first half of 1967, a low-key state of war existed between Syria and Israel. Conflict over Israeli cultivation of land in the Demilitarized Zone led to 7 April pre-war aerial clashes between Israel and Syria. When the Six-Day War broke out between Egypt and Israel, Syria joined the war and attacked Israel as well. In the final days of the war, Israel turned its attention to Syria, capturing two-thirds of the Golan Heights in under 48 hours. The defeat caused a split between Jadid and Assad over what steps to take next.
