The changes in power concept; the Hard to the Soft Power and the Usage of Soft power by United States o America on Iran

At the advent of Islamic Revolution in Iran there was a very crucial conflict between Iran and the division of power in the world. Joseph Samuel Nye has divided the power into two kinds, the soft and the hard power. Military and economic power as the hard and semi-hard power may lead people to change their positions. Soft power is power is the ability to influence the behavior of others to get the outcomes you want, not by forcing or rewarding other but by attracting people. After revolution the American policies put National security of Iran in jeopardize several times. Iran and the united state of America have had ups and downs in their relationship during the last 7 decades. They have experienced the strategic alliance as well as severing diplomatic relations and even imposing the military conflicts. The study of the relations between two countries have indicated that united state have tried to use hard power at the advent of the revolution in Iran such as Economic sanctions, military attack in Tabas and American cooperation with Iraq during the Iran–Iraq War. But these strategies ended in failure then the United States of America adopted some new policies such as soft power against Iran; accordingly the U.S policy towards Iran especially after September eleven has been a mixture of hard and soft measures. Hence their soft power may justify using of the hard power.
