The U.S. Treasury will substantially increase sanctions against Iran. In addition to economic sanctions, the United States has many other ways to restrain its opponents, such as military sanctions and political isolation.

Let's look at the specific measures taken by the United States to sanction Iran. US sanctions against Iran began after the Islamic Revolution in Iran worsened in the United States and Iran. By the time of 1996, the US Congress had also passed a bill specifically targeting Iran, namely the Iran-Libya Sanctions Act. During this period, various US sanctions against Iran reached the peak of US sanctions against Iran.

1979, the United States decided to impose sanctions on Iran for detaining diplomats of the US Embassy in Iran. President Carter of the United States used the second section of the Arms Export Control Law to announce that the United States would stop sending weapons and accessories worth $300 million to Iran, and then the United States also stopped importing crude oil and petroleum products from Iran. At the same time, it also prohibits the United States and its free trade zone from holding Iranian oil products, which can be said to be the total control of Iranian oil by the United States.

1979 and 1986, respectively, the United States frozen all the assets of Iran and Libya in the United States, and the United States frozen the assets of almost most countries in the world during World War II.

While imposing sanctions on Iran, the United States is also actively seeking strong support from its allies. 1979, the U.S. secretary of state visited France, Germany, Britain, Italy and the support of the NATO Council in Brussels, demanding that these countries impose sanctions on Iran at the same time, freeze Iran's domestic assets and restrict its import and export. Of course, the United States did not succeed.
