Title:
1973_oil_crisis

Context:
In the United States, scholars argue that there already existed a negotiated settlement based on equality between both parties prior to 1973. The possibility that the Middle East could become another superpower confrontation with the USSR was of more concern to the US than oil.

In the US production, distribution and price disruptions "have been held responsible for recessions, periods of excessive inflation, reduced productivity, and lower economic growth."
