US President Donald Trump has said the military campaign against Iran is close to conclusion, telling CBS News journalist Weijia Jiang in a phone interview on March 9.

He said that the country had been stripped of its key military capabilities, triggering an immediate collapse in global oil prices.

"I think the war is very complete, pretty much. They have no navy, no communications, they've got no Air Force," Trump said, adding that the US was "very far" ahead of the four-to-five week timeframe he had initially projected for the operation.

Brent crude fell from $99 to $83.9 per barrel within 15 minutes of Trump's remarks being published, before partially recovering to $88.6.

The drop came after Brent had earlier on March 9 topped $119 per barrel for the first time since June 2022, as markets priced in the risk of prolonged disruption to Gulf energy supplies.

Iran willing to de-escalate

Iranian President Masoud Pezeshkian also said he has identified the conditions under which the Islamic Republic is ready to de-escalate the conflict with the United States and Israel on March 9.

"Iran has always stated its readiness to reduce tensions in the region, provided that the airspace, land, and territorial waters of our neighbors are not used to attack the Iranian population," Pezeshkian's press service quoted him as saying.

The US and Israel are also trying to destabilise Iran's relations with its regional neighbours. As an example, he cited Tehran's accusations of attacks on Turkey.

Putin between Iran and US

Russian President Vladimir Putin and US President Donald Trump held their first telephone conversation of 2026 on March 9, with the Iran conflict taking centre stage, Russian presidential aide Yuri Ushakov told RIA Novosti.

The call, the eleventh between the two leaders, was initiated by Trump and described by Ushakov as businesslike and constructive. The discussion focused on the situation surrounding the conflict with Iran, alongside ongoing bilateral negotiations on a Ukrainian settlement.

Putin put forward a number of ideas aimed at a speedy political and diplomatic resolution of the Iran situation, according to Ushakov.

Trump's remarks come as Iranian Foreign Minister Abbas Araghchi warned earlier on March 9 that Tehran retained "many surprises in store" and remained fully prepared to respond to what he described as American plots against the country's oil and nuclear facilities.

Araghchi had said oil prices had doubled since the start of what he called "Operation Epic Mistake", and that any US strike on Iranian energy infrastructure could prompt Tehran to retaliate against corresponding sites across the region. Market analysts had warned such a scenario could drive prices beyond $200 per barrel.
