Iranian President Masoud Pezeshkian said Monday that Iran does not seek a wider war in the Middle East and that such a conflict would have no winners.

“We don’t want war. … We want to live in peace,” Pezeshkian told reporters during a visit to New York for the U.N. General Assembly meeting.

“We don’t wish to be the cause of instability in the region.”

Pezeshkian called for dialogue to resolve the volatile situation in the Middle East and blamed Israel for stoking tensions and instigating conflict, citing assassinations in Tehran and elsewhere that he said Israel had carried out.

“We know more than anyone else that if a larger war were to erupt in the Middle East, it will not benefit anyone throughout the world. It is Israel that seeks to create this wider conflict,” he said.

U.S. officials fear the prospect of an all-out war between Israel and Hezbollah, the Lebanese militant group backed by Iran. Israeli airstrikes killed more than 180 people and wounded almost 730 on Monday, Lebanon’s Health Ministry said, a dramatic expansion of Israel’s aerial attack.

Pezeshkian also slammed the U.S. and other Western countries for what he called double standards as they criticized Iran over human rights but ignored Israel’s “atrocities” in Gaza.

Asked about the possibility of negotiating a new agreement with the U.S. about its nuclear program, Pezeshkian said Iran is interested not in a new nuclear deal but in a return to the 2015 nuclear accord that the U.S. pulled out of in 2018.

“Let’s go back to step one,” he said.

If all sides lived up to that agreement, Tehran might consider new talks, he said.

Pezeshkian, who was elected this year and portrays himself as a relative moderate, also said Iran could not dictate to Houthi forces that are attacking shipping in the Red Sea. The Houthis, he said, were reacting to what he called the unjust plight of Palestinians in Gaza.

“How can we ask them to abstain?” he said. “They are trying to stop genocide.”

Pezeshkian, asked about assessments by U.S. intelligence agencies that Iran was trying to promote campus protests in the U.S. against Israel, rejected the accusation and said it was “childish.”

People around the world are protesting because they are outraged at the situation in Gaza and do not need to be bribed to take to the streets, he added.

The U.S. and its allies say Iran has supplied Russia with armed drones and ballistic missiles for its war against Ukraine, which Pezeshkian denied.

He said Iran opposes “Russian aggression” against Ukraine and called for dialogue to resolve the conflict.

In an interview with NBC News’ Andrea Mitchell, Iran’s vice president for strategic affairs, Mohammad Javad Zarif, echoed Pezeshkian’s comments and said his government was ready to work with other countries to end the conflict in Gaza.

“We want to move in a more peaceful, more stable world for our citizens and for the citizens of the world. We don’t seek war, but we will defend ourselves,” Zarif said.

Zarif also said Iran had the right to retaliate at a time of its choosing over what he called a clear violation of Iran’s sovereignty when the head of Hamas, Ismail Haniyeh, was assassinated in the capital, Tehran, in July. Iran has blamed Israel for orchestrating the bombing. Israel has not publicly confirmed it was behind the attack. 

After the assassination, Zarif said, “we were asked by the international community to exercise restraint in order to bring about an end to the war in Gaza.” But the promise of a cease-fire deal never materialized, he said.

Zarif played a leading role in the negotiations for the 2015 nuclear deal between Iran and world powers when he was foreign minister. The agreement imposed strict limits on Iran’s nuclear program in return for an easing of U.S. and international sanctions. 

The Biden administration has expressed concern about Iran’s advancing nuclear program and its restrictions on U.N. inspections of nuclear sites. Secretary of State Antony Blinken has said Tehran could produce enough weapons-grade uranium for an atomic bomb within a week or two if chose to do so.

Zarif said the U.S. had only itself to blame, as he said it was the U.S. that withdrew from the 2015 nuclear accord during President Donald Trump’s administration.

“It was the miscalculation of the Trump administration that withdrew from the nuclear deal. It has been a lose-lose situation,” Zarif said.

Earlier Monday, Iranian Foreign Minister Abbas Araghchi said Tehran was “focused on initiating a new round of nuclear negotiations.”

“We are prepared, and if the other parties are also prepared, we can have another beginning of the talks during this trip,” he said in a video on Telegram, adding that he planned to stay in New York for an extended period.

Trump withdrew the U.S. from the landmark Obama-era deal in 2018, complaining about Iran’s ballistic missile program and its deepening influence in the region. The move dismayed some American allies and prompted fury in Iran.

The U.S. is not expecting to talk to the Iranian government any time soon, a senior Biden administration official said Monday.

The official said the U.S. continues to signal to Iranian officials what is expected if its leaders are serious about changing the country’s standing in the international community. Yet Iran is selling ballistic missiles to the Russian government, the U.S. official said, a move that fuels the war in Ukraine.

The International Atomic Energy Agency has warned of Iran’s continued enrichment of uranium beyond the needs of commercial nuclear use. Meanwhile, Iran has also blocked U.N. inspectors from visiting some sites in its nuclear program.

The full extent of Iran’s nuclear capabilities remains unclear. Iran has maintained that its nuclear program is for civilian, not military, purposes.

Iran appears to be shifting its stance as Israel’s monthslong deadly offensive in Gaza nears the one-year mark after the Hamas-led Oct. 7 attacks.

It also comes as the U.S. prepares for a presidential election, now just weeks away.

In his comments, Araghchi said the “international situation” could make it “difficult to start the negotiations.”
