In his attempt to free the Americans taken hostage by Iran, President Carter convinced US allies to boycott Iranian goods.

Carter, in April 1980, broke diplomatic relations with Iran and imposed a trade embargo, except for medicine and food. Iranian funds in the US were frozen and accounted for to compensate the hostages when they were released and to pay the demands of US companies against Iran.

interdependence is when all participating groups and individuals depend on each other. if you depend on one anothers goods, you end up trading in order to get the items you're looking for. (for ex: if i have food and you have water, we trade in order to depend on each other to live)
