As the U.S.–Saudi relationship was growing slowly, World War II was beginning its first phase, with Saudi Arabia remaining neutral. The U.S. was deeply involved in World War II, and as a result, U.S.–Saudi relations were put on the 'back burner'. This negligence left Saudi Arabia vulnerable to attack. Italy, an Axis power, bombed a CASOC oil installation in Dhahran crippling Saudi Arabia's oil production. This attack left Bin Saud scrambling to find an external power that would protect the country, fearing further attacks that would most likely cease the country's oil production and the flow of pilgrims coming into Mecca to perform Hajj, the basis of the Saudi power and economy at that time.
