Trump's recent decision to potentially end the agreement marked a significant shift in US foreign policy amid tensions with North Korea. This move came shortly after he targeted Barack Obama's healthcare reform, showing a pattern of dismantling his predecessor's policies. The deal, which involved multiple countries, was designed to prevent Iran from obtaining nuclear weapons, but Trump criticized it as being too lenient. He expressed concerns about the potential consequences of allowing Iran to continue its nuclear program. European allies are cautioning about a potential rift with the US due to President Trump's decision to put the nuclear agreement in limbo, which they believe undermines US credibility globally. Trump's focus on "America First" has also led to the US withdrawing from the Paris climate accord and the Trans-Pacific Partnership trade talks, as well as renegotiating NAFTA. Iran's President Rouhani has responded by affirming Iran's commitment to the deal and criticizing Trump's unfounded accusations, stating that Iran will not succumb to foreign pressure. He believes that Iran and the deal are now even stronger. The head of the UN nuclear watchdog confirmed that Iran is following the strictest nuclear verification regime in the world and is abiding by the agreement.

According to Yukiya Amano, director general of the International Atomic Energy Agency, Iran has fulfilled its nuclear-related commitments under the JCPOA, as the deal is formally known. It is required by US law for the president to certify to Congress every 90 days that Iran is upholding the agreement, a task which Trump has done reluctantly on two occasions. Two officials within the administration knowledgeable about the Iran policy debate revealed that Trump disregarded the advice of his secretary of defense, secretary of state, the chairman of the Joint Chiefs of Staff, his chief of staff, and his national security advisor. Instead, Trump favored the more hardline views of CIA Director Mike Pompeo and some external sources. US Democrats criticized Trump's choice, with Senator Ben Cardin stating that the decision will only serve to further isolate the US from its allies and partners, especially at a time when there is a nuclear crisis with North Korea. EU foreign policy chief Federica Mogherini in Brussels also expressed disbelief at Washington's unilateral decision to cancel the accord, emphasizing the importance of maintaining a working nuclear agreement. This agreement is not between two parties. The US Congress has the authority to determine whether economic sanctions on Tehran, which were previously lifted, should be reinstated. If Congress chooses to reinstate the sanctions, the United States would be breaching the terms of the nuclear deal, potentially causing it to collapse. If Congress takes no action, the agreement will continue as is.

Bob Corker, the chairman of the Senate Foreign Relations Committee, is working on amending a law regarding Iran to include "trigger points" that, if crossed by Tehran, would result in the automatic reimposition of US sanctions. A protestor wearing a Donald Trump mask demonstrated outside the White House in opposition to President Trump's announcement about the Iran nuclear deal and his policy towards Iran. The triggers being considered include reimposing US sanctions if Iran is deemed to be less than a year away from developing a nuclear weapon, as well as addressing tougher nuclear inspections, Iran's ballistic missile program, and the elimination of the deal's "sunset clauses." The passing of this legislation by Congress is uncertain. Trump cautioned that if a resolution cannot be reached with Congress and allies, the agreement will be ended. He specifically targeted Iran's Islamic Revolutionary Guard Corps for sanctions and strongly criticized Tehran for its actions in Syria, Yemen, and Iraq. While the Trump administration condemned the Revolutionary Guards, it did not classify them as a foreign terrorist organization. The group holds significant power in Iran's security, political, and economic systems and greatly influences the country's domestic and foreign policies. Although the United States had previously imposed sanctions on the Revolutionary Guards, the recent measure is expected to have mostly symbolic effects. The US military announced on Friday that it was exploring new opportunities to collaborate with allies in order to increase pressure on Iran in alignment with Trump's new strategy. Additionally, they were assessing the deployment of US forces. However, US Defense Secretary Jim Mattis noted that Iran had not yet engaged in any provocative actions in response to Trump's declaration.
