Strategic role of congress in impose of U.S policies against Iran in era of Obama

Although the Obama administration was able to carefully apply its sanctions policies against Iran, but many sanctions have been imposed on Iran by Congress. Recognizing the true role of Congress in Iran can make the decision-making process of Iran's foreign policy more effective in dealing with threats. Experiences have shown that whenever Congress has embarked on US policies towards Iran, its behavior toward Iran has been accompanied by more stringent policies. The study seeks to examine the real role of Congress in Obama's time toward Iran to help identify the real elements of the threat to Iran's national interests. The research therefore seeks to answer the question of how much of Congress has played a role in defining US policy toward Iran during Obama's time. Referring to the texts of the hearings and the laws passed by the Congress, the answer is that Congress has played a pivotal role in determining US policy toward Iran and has tried to get the top hand in the matter with the president.
