An oil embargo is a restriction placed on the export or import of oil, often imposed by one country or a group of countries against another. This action is typically taken to exert political pressure or to respond to specific actions, such as military aggression or human rights violations. The goal is to limit the targeted country's access to oil, which is crucial for its economy and military operations. Historically, oil embargoes have had significant impacts on global markets and economies. For example, the 1973 Oil Crisis saw an embargo by OPEC nations against countries supporting Israel, leading to skyrocketing oil prices and fuel shortages in many parts of the world. Such measures can create economic instability and prompt countries to seek alternative energy sources.
