Iranian President Hassan Rouhani said in a new interview aired on Monday that the U.S. would pay “a high cost” should it withdraw from the 2015 nuclear accord reached under former President Barack Obama Barack Hussein ObamaMomentum growing among Republicans for Supreme Court vote before Election Day Warning signs flash for Lindsey Graham in South Carolina Majority of voters say Trump should not nominate a Supreme Court justice: poll MORE.

"Exiting such an agreement would carry a high cost for the United States of America, and I do not believe Americans would be willing to pay such a high cost for something that will be useless for them,” Rouhani said during an interview on CNN International’s “Amanpour,” scheduled to air Monday afternoon.

The comments from Rouhani come ahead of President Trump’s first address to the United Nations General Assembly on Tuesday, where Trump is expected to discuss ongoing tensions with Iran.

Iran often warns of consequences should the U.S. exit the agreement, which was negotiated between Iran, the U.S. and international powers to curb Tehran’s nuclear program in exchange for sanctions relief.

Rouhani also said that discarding the nuclear deal "will yield no results for the United States but at the same time it will generally decrease and cut away and chip away at international trust placed in the Unites States of America."

Trump has repeatedly criticized the nuclear deal with Iran and during his presidential campaign vowed to tear it up once he took the Oath of Office.

The Trump administration is said to be considering a more aggressive strategy toward Iran.
