The intention of the United States to break the treaty will become clearer if the senior officials impose sanctions on them. Since the beginning of this year, the United States has continued to exert pressure on the Iranian nuclear issue. In March 2018, Trump drastically adjusted his diplomatic team to replace Tillerson, his disagreed Secretary of state on the Iranian nuclear issue, to nominate the Secretary of state, who advocated a tough attitude towards Iran. On the 22 day, Trump also nominated John Bolton, the war hawk, as assistant to the presidents national security affairs. On the 23 day, the United States offered a sanction stick for sanctions against Iran on the grounds of suspected malicious network activities. In the face of a recent visit to the United States, Mucklow, President of France, in the face of saving the Iranian nuclear agreement, Trump was angry with the Iraqi nuclear agreement, saying that the nuclear agreement was a terrible deal, it should never be signed, and the remarks were the last chance to revise the agreement to the European home at the beginning of the year. Trumps attitude towards withdrawal from the Iranian nuclear agreement has become increasingly tough. Facing the pressure of the United States, Iran is uncompromising and has a clear attitude. Faced with the continued pressure from the United States on the issue of the Iranian nuclear agreement, Iran stands firm and uncompromising. In April 8th, Salehi, chairman of the Iran atomic energy organization, said that if the western countries abandoned the Iran nuclear agreement, Iran would restart 20% enrichment uranium enrichment activities within 4 days. On the 24 day, President Rouhani of Iran warned us president Trump not to withdraw from the Iran agreement on nuclear issue or face serious consequences. On the same day, the Secretary General of the Supreme National Security Council of Iran, Ali Shamkhani, pointed out that if the national interests were threatened, Iran could withdraw from the Treaty on the non proliferation of nuclear weapons. While demonstrating his position, Iran is also making clear its attitude through practical action. In April 18th, the military parade in Iran was held to display a variety of main combat equipment made or introduced by Iran. On the parade, President Rouhani attacked the United States and its allies against Syria as aggressive behavior. Will Trump really withdraw from the Iran nuclear agreement? May 12th is the deadline for the sanctions exemption period of the Iran nuclear issue. Will the us take the lead in the world and insist on breaking the treaty? Some comments have pointed out that unilateral withdrawal from the Iranian nuclear agreement is extremely harmful to the United States, so the United States will not really withdraw from the Iran nuclear agreement. The reason why the United States has ruthless words on the issue of nuclear agreement and abolishment of the Iraq nuclear agreement is to revise the agreement, contain the reality of Iran and seize greater interests by the name of destroy the contract. There are four reasons why Trump has not withdrawn easily from the Iran nuclear agreement. First, the withdrawal of the Iranian nuclear agreement will reduce the credibility and international credibility of the United States in the international community, which will greatly damage the international image of the United States. As a contracting state signed in July 2015, the United States retreats and retire in the absence of the ink of the treaty, and its international image will inevitably suffer great damage. Darrell West, a senior fellow at the Brookings Institution of the US think tank, said that the Trump administrations frequently threatened tearing up the Iraq nuclear agreement and reopening the sanctions against Iraq have made the situation in the Middle East unstable and greatly undermined the global credibility of the United States. Second, the withdrawal of the Iraq nuclear agreement will jeopardize the national security of the United States and its national interests in the Middle East. Once the nuclear program restarted as a military power in the Middle East, it is bound to pose a serious security threat to the military existence of the United States in the Middle East and even to the United States of America. Chinas former ambassador to Iran, Hua Liming, said, if Iran also steps in the United States, unilaterally announces the destruction of the agreement and restarts the nuclear program, then the consequences will be unthinkable. At the same time, Iran, as a regional power, plays a decisive role in Syria, Iraq and Yemen. It is in the interests of the United States to cooperate with Iran in the conflict zone. If Iran gets away from the international system or starts a new business, it will damage the interests of the United States in the Middle East. Third, the withdrawal of the Iranian nuclear agreement will increase the gap between the United States and the European Union. Just like the German Chancellor Merkel, who is about to visit the United States, is consistent with the statement that the Iranian nuclear agreement is stronger than nothing. The Iranian nuclear agreement is in line with the interests of the European Union. In the face of the constant pressure from the United States, the EU countries such as France and Germany have been trying to mediate, hoping to meet the demands of the United States as much as possible to maintain the existence of the nuclear agreement. If the United States alone to quit the Iraq nuclear agreement, then the EU countries will have skin pain, Trump after the power of the United States and the EU will be further deepened. Fourthly, withdrawal from the Iran nuclear agreement is not an end, but a means. The United States wants to threaten Iran with a breach of contract, forcing the United States to accept the amended treaty or the new version of the Iranian nuclear agreement that the United States is satisfied with, so as to achieve the purpose of containment of Iran. Trump made a speech at the end of 2017, saying that the United States and its allies have realized that the main contradiction in the Middle East is no longer a Palestinian Israeli conflict, but a threat from Iran. Faced with the threat of Iran, the Iranian nuclear agreement as one of the political legacy of former US President Obama has become the only option to contain Iran. As a multilateral treaty, unilateral exit is extremely costly for the United States. Therefore, the revision of the agreement to make it conform to the interests of the United States and compel Iran to surrender is the best option. In an interview in February 2018, former Secretary of state Tillerson said: the president said that either the agreement should be amended or the agreement should be abolished. We are trying to fulfil his promise to achieve the former. On the issue of the abolition of the Iran nuclear agreement, the United States should respect international consensus and abandon unilateralism. Otherwise, the loss of people is also not selfish!
