Detailed explanation-1: -During the 1973 Arab-Israeli War, Arab members of the Organization of Petroleum Exporting Countries (OPEC) imposed an embargo against the United States in retaliation for the U.S. decision to re-supply the Israeli military and to gain leverage in the post-war peace negotiations.

Detailed explanation-2: -The 1973 oil crisis or first oil crisis began in October 1973 when the members of the Organization of Arab Petroleum Exporting Countries (OAPEC), led by King Faisal of Saudi Arabia, proclaimed an oil embargo. The embargo was targeted at nations that had supported Israel during the Yom Kippur War.

Detailed explanation-3: -The embargo caused the United States and western European countries to reassess their dependence upon Middle Eastern oil. It also led to far-reaching changes in domestic energy policy, including increased domestic oil production in the United States and a greater emphasis on improving energy efficiency.

Detailed explanation-4: -The 1973 crisis resulted from cuts in domestic oil production, whereas the 1979 crisis was the result of the Yom Kippur War. The 1973 crisis was more severe than the crisis of 1979. Both crises led to reduced regulations to expand domestic oil production.
