Trump sought options for attacking Iran last week, but held off: report

President DonaldTrump, with two months left in office, last week asked for options on attackingIran's main nuclear site, but ultimately decided against taking the dramatic step, a U.S. official said on Monday.

Trumpmade the request during an Oval Office meeting on Thursday with his top national security aides, including Vice President Mike Pence, Secretary of State Mike Pompeo, new acting defence secretary Christopher Miller and General Mark Milley, chairman of the Joint Chiefs of Staff, the official said.

Trump, who has refused to concede and is challenging the results of the Nov. 3 presidential election, is to hand over power to Democratic president-elect Joe Biden on Jan. 20.

The official confirmed the account of the meeting in The New York Times, which reported the advisers persuadedTrumpnot to go ahead with a strike because of the risk of a broader conflict.

"He asked for options. They gave him the scenarios and he ultimately decided not to go forward," the official said.

The White House declined comment.

Trumphas spent all four years of his presidency engaging in an aggressive policy againstIran, withdrawing in 2018 from theIrannuclear deal negotiated by his Democratic predecessor, Barack Obama, and imposing economic sanctions against a wide variety ofIranian targets.

Trump's request for options came a day after a UNwatchdog report showedIranhad finished moving a first cascade of advanced centrifuges from an above-ground plant at its main uranium enrichment site to an underground one, in a fresh breach of its 2015 nuclear deal with major powers.

Alireza Miryousefi, spokesman forIran's mission to the United Nations in New York, saidIran's nuclear program is purely for peaceful purposes and civilian use andTrump's policies have not changed that. "However,Iranhas proven to be capable of using its legitimate military might to prevent or respond to any melancholy adventure from any aggressor," he added.

Iran's 2.4 tonne stock of low-enriched uranium is now far above the deal's 202.8 kilogram limit. It produced 337.5 kilogramsin the quarter, less than the more than 500 kilograms recorded in the previous two quarters by the International Atomic Energy Agency.

In January,Trumpordered a U.S. drone strike that killedIranian Gen.Qassem Soleimani at Baghdad's airport. But he has shied away from broader military conflicts and sought to withdraw U.S. troops from global hotspots in keeping with a promise to stop what he calls "endless wars."

A strike onIran's main nuclear site at Natanz could flare into a regional conflict and pose a serious foreign policy challenge for Biden.

Biden's transition team, which has not had access to national security intelligence due to theTrumpadministration's refusal to begin the transition, declined comment.
