When you look at the powers of different presidents, you need to look at their responsibilities and how much power they actually have when it comes to decision-making. The Iranian and American presidents have two different presidential powers, formal and informal. Formal powers are those that are enshrined in the constitution and must be respected by anyone gaining power. For example, both presidents can sign treaties with foreign countries. Informal power is not explicitly written into the constitution (1), but is exercised by the president, for example being persuasive, it is a power they must use because that is how they will get the presidential role , persuading the public and entering into the international treaties they need to use the The United States President, currently Barack Obama, has executive powers over the federal government and has the power to appoint ambassadors, the Cabinet, judges of the Supreme Court, federal court judges and controls the armed forces. strengths. In the development of a law, the president himself is only part of the final process: when it comes to writing it down (3), he has the power to "forget it" because that he has the authority to leave it on his desk for 10 days, then have him start the process again. This shows that the American president has the power to “delay” the adoption of a law. Compared to the Iranian president, currently Hassan Rouhani, the American president has more formal powers because, although Rouhani is the head of the executive branch, the Supreme Leader sets general policies and oversees everything the president does. In contrast, Iran's supreme leader appoints key figures in the political system, not the president. (2). This does not mean, however, that the American president can do whatever he wants; The Senate must approve presidential appointments and approve treaties, the Senate must also approve the appointments of all supreme leaders. The President of the United States can enter into executive agreements (equivalent to a treaty) and meet with other world leaders without Senate approval. He also has powers that allow him to gain control in an emergency, without interference from Congress. Abraham Lincoln used it during the Civil War because he needed to make sure he could spend all the money he needed to win the war. The Iranian president can also do this, he can declare a state of emergency which suspends all laws and declare a state of martial law. However, no president has yet used this power. However, the Iranian president cannot make any decisions without obtaining their approval, because he is not the highest official in the Iranian political system, unlike the Supreme Leader, and he must approve all treaties and policies that the president wishes to adopt. Informal and formal powers are not the only means by which the power and accountability of the president can be hindered or
