As a party to the Iran nuclear agreement, the United States unilaterally withdrew from the agreement in 2018 and restarted sanctions against Iran. But for trump, who is about to face an election vote, an exit from the deal is not enough. According to Reuters on August 21, U.S. Secretary of state pompeio formally submitted a notice to the UN Security Council on Thursday accusing Iran of violating the provisions of the Iran nuclear agreement and demanding that the United Nations resume all sanctions against Iran. According to the resolution, if Iran abides by the terms of the Iran nuclear agreement, the UN arms embargo on Iran will expire on October 18, 2020. After the expiration, countries can resume arms sales to Iran. The resolution also states that once the “participating States” of the Iran nuclear agreement determine that Iran has seriously violated the provisions of the agreement, they can submit a written complaint to the Security Council. Complaints will trigger a quick recovery of sanctions. < / P > < p > after the written complaint is submitted, the 30 day countdown will start. During these 30 days, any member of the Security Council can propose a resolution calling for the continued lifting of the arms embargo against Iran. < / P > < p > if no member states propose a resolution within the first 10 days, the president in office of the Security Council will initiate the resolution within the countdown period for Member States to vote. < / P > < p > in this way, after the 30 day countdown period, in theory, the UN arms embargo against Iran will remain in force after October. This will further push the Iran nuclear agreement to death. However, it is not easy for the United States to keep the UN arms embargo in force because the United States has withdrawn from the Iran nuclear agreement and other parties to the agreement are not willing to void it. < p > < p > China calls on Indonesia, the rotating president of the Security Council, not to regard the notification of the United States as triggering the rapid resumption of sanctions mechanism, and suggests that Indonesia should discuss with members of the Security Council when dealing with the matter. < / P > < p > the three countries issued a joint statement, pointing out that the United States has withdrawn from the Iran nuclear agreement in 2018 and is no longer a party to the agreement, and has no position to trigger the rapid recovery of sanctions mechanism. The three countries also reiterated their support for the Iran nuclear agreement. However, the United States maintains that Security Council resolution 2231 clearly states that as long as it is a “participating country” of the agreement, it can lodge a complaint, and the resolution does not mention the withdrawal of the participating countries from the agreement. When the resolution was passed, the United States was one of the participating countries. This is equivalent to recognizing that the United States, which has withdrawn from the Iran nuclear agreement, is qualified to trigger the rapid resumption of sanctions mechanism, and even if a resolution is proposed, it will be rejected by the United States. However, pompeio said confidently that a new resolution would be proposed later, and he did not disclose which country it was. In an interview with Reuters, European diplomats speculated that Indonesia, as the rotating chairman, should not initiate the resolution due to the opposition of most member states. < / P > < p > if other countries do not mention it, the United States can also propose its own resolution and then veto it. But this kind of operation will cause a series of complicated procedural disputes. < p > < p > within 30 days of countdown, if all countries fail to reach an agreement, the United States can declare the UN arms embargo against Iran to continue in force after 30 days; other countries can ignore the US statement and cancel the arms embargo against Iran after October. Regardless of the outcome, the United States is bound to implement the UN arms embargo. In addition to further squeezing Iran, the U.S. action will also pose a threat to the countries dealing with Iran, and other countries will face the joint attack of US sanctions. The United States hopes that the arms embargo on Iran will overturn the Security Council’s approval of the Iran nuclear agreement. Iran, which continues to be hit, withdraws from the Iran nuclear agreement and completely resumes its nuclear program in anger, which means the end of the Iran nuclear agreement. After the U.S. withdrew from the Iran nuclear agreement and restarted sanctions against Iran, Iran has gradually reduced the implementation of the terms of the agreement, but has not taken major actions. European countries have been in communication with Iran, hoping to keep the Iran nuclear agreement. US presidential candidate Biden has said that if Iran can strictly implement the terms of the agreement after his election, the United States will return to the Iran nuclear agreement. The Iran nuclear deal was one of Obama’s important achievements, when Biden was vice president of the United States. Last week, the United States proposed to extend the U.N. arms embargo on Iran, but suffered a crushing defeat in the Security Council vote. Of the 15 members of the Security Council, only the United States and Dominica voted for it. On Thursday, Iran announced two new missiles, a ballistic missile with a range of 1400 km and a sea launched cruise missile with a range of 1000 km. The US military bases in the Middle East are within the range of the two missiles. In January this year, Sulaimani, commander of the “Holy City Brigade” of Iran’s Islamic Revolutionary Guard, and muhandis, commander of the pro Iran Iraqi militia, both died in US air strikes, further aggravating the confrontation between the United States and Iran.
