Embargoes function as a political tool by restricting trade with specific countries to exert pressure and influence their policies. Nations implement embargoes to respond to actions deemed undesirable, such as human rights abuses or aggression. By limiting access to goods and services, embargoes aim to weaken the targeted country's economy and prompt a change in behavior. However, the effectiveness of embargoes can vary, as they may lead to hardship for civilians without significantly altering the actions of those in power. Understanding their implications is crucial for evaluating foreign policy strategies.
