The war began on 6 October 1973, when the Arab coalition jointly launched a surprise attack against Israel on the Jewish holy day of Yom Kippur. Egyptian forces crossed the Suez Canal in Operation Badr and advanced into the Sinai Peninsula; the Syrians launched a coordinated attack in the Golan Heights to coincide with the Egyptian offensive and initially made gains into Israeli-held territory. This Israel ignored reports of an impending Arab attack . Although the Arabs were pushed back Israel was uncertain of it's ability keep at the Arabs at back because of their early successes which resulted in the 1978 Camp David Accords that followed the war, Israel returned the entire Sinai Peninsula to Egypt. But What if Israel believed the reports of Arab attacks and prevented them from making any gains while pushing them back ?
