Step-by-step explanation:
Sanctions against nations are a form of trade restriction that has economic and political impact. They are used by one nation or group of nations to punish another nation for a particular behavior or policy. Sanctions can take various forms, such as economic boycotts or the suspension of trade and financial relationships.
For example, the United States and other countries implemented an economic boycott of Iran to pressure it to halt its nuclear energy program. In the recent Iran nuclear deal, Iran agreed to halt nuclear development in exchange for the lifting of economic sanctions.
Sanctions can be an effective tool in international relations, as they can exert pressure on a targeted nation to change its behavior. However, they are not always guaranteed to succeed, and the effectiveness of sanctions depends on various factors such as international support and the willingness of the targeted nation to comply.
