Political map of the Eastern Mediterranean 24 October 1973 (Yom Kippur War: Israeli Counterattack): The Arab successes in the Yom Kippur War lasted just a few days before Israel was able to regain the initiative and launch counteroffensives, trapping the Egyptian Third Army east of the Suez Canal (Operation Abirey-Halev) and invading Syria (Yom Kippur War). By 25 October Egypt and Syria had agreed to UN-backed ceasefires—although the devastating oil embargo the Arab oil producing nations had placed on the US and its allies in retaliation for their support of Israel (1973 oil crisis) would last until March 1974.
