Answer:
This 1987 excerpt best describes how the United States uses its economic powers to punish governments that encourage terrorism.
Step-by-step explanation:
This 1987 excerpt was written by President Ronald Reagan with the aim of pointing to Iran as a government that encourages terrorism and therefore must be punished commercially, as a way to force that government to exterminate its violence in criminal acts, such as terrorism.
This punishment occurred with the import ban, that is, the purchase by the American government, of any item of Iranian origin. This shows how the United States used its economic power to establish policies. This is because in addition to preventing the purchase of Iranian products, the US influences other countries not to buy these products, due to their influence.
