Iranian Foreign Minister Abbas Araghchi said Sunday that Iran is “fully prepared” if President Trump orders fresh strikes against the Iranian regime following the November midterm elections.

In an interview with NBC News’s Kristen Welker on “Meet the Press,” Araghchi said the United States has “tested us in their aggression” as well as through diplomatic efforts. He said that despite Trump rejecting Iran’s seven-day proposal to reopen the Strait of Hormuz and establish a ceasefire, Tehran’s offer remains on the table.

“We are fully prepared for the war to be resumed,” Araghchi told Welker. “And I repeat, we stand firm in the face of any new aggression, even if it comes to a doomsday war. But at the same time, we stand ready for diplomacy. It is up to President Trump to choose.”

Araghchi acknowledged that Trump had rejected the proposal but said Iranian negotiators are still waiting “for an official response through the mediators.”

The foreign minister said any further fighting would resemble earlier exchanges of strikes, while emphasizing that Iran’s military has “changed our tactics, and we are fully prepared to do that.”

Araghchi defended Iran’s nuclear enrichment activities, saying the program is legal and serves “certain” purposes, including “medical purposes and other purposes.” Welker challenged that position, pointing out that Iran’s 60 percent enrichment level is 20 times higher than what is required to generate electricity. She then asked whether Tehran would permit the United States to remove its enriched uranium as part of an agreement to end the hostilities.

“We have removed any concern in our past negotiations,” Araghchi said. “If there is still such a question, then why did they bomb us? Are they allowed to bomb anything that they think is illegal, or there is no justification for that? War is not a solution. That was a subject for negotiation, and we did it in the past.”

Welker also questioned Araghchi about the condition of Iranian Supreme Leader Mojtaba Khamenei, who was reportedly seriously wounded in U.S.-Israeli airstrikes on Feb. 28. Those strikes killed his father and predecessor, Supreme Leader Ayatollah Ali Khamenei, along with several members of the family.

Mojtaba Khamenei is believed to remain in hiding and has not appeared publicly or been photographed since taking over from his father. Araghchi attributed his absence to “security reasons,” citing “indications” that the United States poses a threat.

“We receive his comments, and orders, and opinions,” he added. “And there is a national consensus on decision-making. It is false if somebody thinks that there are different sources of power inside Iran. We move based on national consensus.”

Iranian President Masoud Pezeshkian told Fox News’s Bret Baier on Thursday that he last met with the younger Khamenei in person roughly a month and a half ago. Asked by Baier whether Khamenei remains capable of governing, Pezeshkian responded, “Very much so, completely.”

Before the United Nations General Assembly, Pezeshkian said Tehran remains open to reaching an agreement before the November midterm elections.
