Officials in Washington are allegedly discussing the possible use of nuclear weapons against Iran as the months-long conflict continues to escalate, former US Congresswoman Marjorie Taylor Greene has claimed.

Greene, once a prominent MAGA ally, made the allegation in a post on X on Sunday. She said the issue had been raised during strategy meetings, but did not identify those involved or provide evidence.

“They are discussing using nuclear weapons on Iran in strategy meetings,” she wrote. “I’m not speculating, I know. And it’s pure evil.”

Greene claimed Washington was considering lowering the threshold for nuclear use despite US President Donald Trump repeatedly declaring victory in the conflict. She warned that such a move could trigger a “nuclear holocaust” and drag the world into a much wider war.

The White House has not publicly confirmed that such discussions are taking place.

Greene has increasingly criticized Trump over the US-Israeli war on Iran, putting her at odds with a political movement she was once closely associated with.

Her warning comes amid reports that Washington has been weighing further escalation in the conflict. The Washington Post reported last month that the US was preparing for a wider war, while the Pentagon has reportedly examined a major ground operation to seize Iran’s enriched uranium.

The US and Israel launched their unprovoked military campaign against Iran in late February, accusing Tehran of being on the verge of creating a nuclear bomb. That was despite US intelligence and the International Atomic Energy Agency (IAEA) stating there was no evidence of an Iranian nuclear weapon program.

Iran retaliated with strikes on American and Israeli targets across the region and later restricted traffic through the Strait of Hormuz.

Washington and Israel have continued to demand “zero enrichment” and the removal of Iran’s enriched uranium stockpile.

Tehran has rejected the demands, insisting its nuclear program is peaceful and enrichment is a sovereign right. At the same time, it has warned that it could reach weapons-grade levels if attacked again, while noting it has made no decision to build a bomb.
