Why did OPEC cut off oil to the West in 1970?

OPEC cut off oil to the West in 1973 as a response to U.S. support for Israel during the Yom Kippur War against Arab nations. This decision was part of an oil embargo aimed at leveraging oil as a political tool to influence Western nations and assert Arab power in the global energy market. The embargo led to significant oil price increases and economic turmoil in many Western countries, highlighting the West's dependence on Middle Eastern oil.
