On Friday, US President Donald Trump confirmed that he has sent a letter to Iran, urging the Islamic Republic to enter into discussions aimed at preventing the development of nuclear weapons.

Trump cautioned that military action could be a possibility if diplomatic efforts do not begin.

Iran’s Foreign Minister Abbas Araghchi responded by stating that the country would not entertain negotiations as long as the US continues its "maximum pressure" strategy, which includes re-imposed sanctions following the US withdrawal from the Joint Comprehensive Plan of Action (JCPOA) in 2018.

Tehran's mission to the United Nations indicated that it had not received any communication from Trump, and the details of how the letter was delivered remain uncertain.

Trump’s approach signifies a departure from the hardline policies of his previous administration and may lead to tensions with key allies, notably Israel, which has carried out military operations against Iranian targets.

In his letter to Iran's Supreme Leader Ayatollah Ali Khamenei, Trump claimed that a negotiated agreement would be highly advantageous for Iran.

He voiced concerns about the consequences of military action: "If we have to go in militarily it's going to be a terrible thing for them," he told Fox Business, stressing that Iran's pursuit of nuclear weapons is unacceptable.

The JCPOA, established in 2015 during Barack Obama’s tenure, aimed to curtail Iran's nuclear program in exchange for the lifting of sanctions.

However, after the US exited the agreement, Iran gradually scaled back its compliance, ultimately enriching uranium to levels close to weapons-grade.

Last month, Rafael Grossi, the chief of the United Nations Atomic Energy Agency, characterized Iran's uranium enrichment at 60 percent as "almost weapon level" and indicated that the JCPOA is no longer effective.

Upon resuming his term in January, Trump reinstated the maximum pressure tactic on Iran, albeit he mentioned that he was doing so reluctantly.

This shift has included distancing himself from advisors associated with his previous stance on Iran.

Against this backdrop, Iran finds itself in a precarious regional situation.

The nation has perceived substantial threats following Israeli airstrikes that have weakened its military capabilities and ongoing regional conflicts.

Moreover, Iran’s alliance with Syrian President Bashar al-Assad has come under strain as Assad's regime has faced significant challenges since December 2022.

Araghchi emphasized Iran’s position against threats and military solutions concerning its nuclear program, asserting that it is a matter of advanced technology inherent within its scientific community.

He did not indicate any willingness to negotiate, suggesting that until US pressure eases, direct talks are not feasible.

Iran has consistently refuted claims of seeking nuclear weapons, with Khamenei previously citing the JCPOA as proof of the United States' unreliability as a negotiating partner.
