The ceasefire agreement with Iran "is over". These were the words of the President of the United States, Donald Trump, in statements prior to the NATO summit that is being held these days in Turkey and after the exchange of attacks between the two countries.

Trump called Iranian leaders “scum” and “crazy,” and said that US negotiators could continue talks “if they wanted to,” but that he considered dealing with the Iranian side “a waste of time.”

“I don’t want to deal with them anymore; they’re scum,” the US president declared during a NATO summit in Turkey. “They’re sick people, they’re led by sick people… As far as I’m concerned, this is over.”

Late Tuesday, the United States reported that it had attacked more than 80 Iranian targets following the attacks on three oil tankers in the Strait of Hormuz. Iran has not directly claimed responsibility for the attacks.

In response, Iran declared that it was attacking US military installations in Bahrain and Kuwait.

Last month, Tehran and Washington signed a 14-page memorandum of understanding with the aim of extending the ceasefire and ending the conflict “on all fronts”.

An agreement that, according to Trump, is now broken. “We made a deal. They [Iran] come out, talk to the press, and say, 'We didn't even talk about it.' Something's wrong with them. They're crazy. As far as I'm concerned, it's over.”

The United States also announced that it had revoked the temporary suspension of sanctions on Iranian oil sales.

Oil prices surged around 6% following Trump's comments, dampening sentiment in other financial markets, although they are still well below the highs reached during the total closure of the Strait of Hormuz, a key shipping lane.

The United States and Iran resumed fighting late Tuesday and into the early hours of Wednesday, in the worst exchange since they signed an interim agreement in June.

Iranian spokesman Mohammad Bagher Ghalibaf accused the United States of violating its Memorandum of Understanding (MoU) on this and other issues, including attacks in southern Iran and the “violation of Iranian agreements in the strait.”

“The era of harassment and extortion is over. It leads nowhere. We will not give up,” he stated.

This is not the first time attacks have occurred since the signing of the memorandum of understanding on June 17.

The United States launched attacks on June 25 after an Iranian missile struck a cargo ship in the Strait of Hormuz, prompting a series of US airstrikes against Iran. By June 29, both sides had agreed to cease hostilities.

One of the 14 points of the Memorandum of Understanding is the “immediate and permanent cessation of military operations on all fronts.”

Both sides had continued negotiations on terms to definitively end the war, but the talks were interrupted during funeral ceremonies held in Iran and Iraq in honor of the late Ayatollah Ali Khamenei, who died on the first day of the US and Israeli attacks on Iran.

Ceremonies are being held in Iraq this Wednesday, and the funeral rites and burial will take place on Thursday in Mashhad, in northeastern Iran.

It is unclear when talks will resume after this latest round of attacks, as Trump responded to a question about whether talks would resume after the funeral with: "I don't care."

“Frankly, I don't want to waste time with them. Now, I will let our wonderful negotiators keep talking if they want to, but I don't see it possible,” Trump said.

“In my opinion, it's a waste of time to deal with them. They're liars.”
