WASHINGTON/AMMAN – US President Donald Trump said Monday that he decided to pause US strikes on Iran in order to give negotiations another chance, while warning that he could order a restart of strikes if talks with Iran fail.

"We are in very deep talks with Iran. If they don't work out, we will go back to very strong military action," Trump said in an interview with US online news outlet Axios.

Asked how long he was willing to give diplomacy, he said, "Not much time. Either it goes fast or not at all."

Trump said he decided to pause strikes on Friday because the countries that are mediating as well as other countries in the region had asked him to give talks with Iran another chance.

Later, the president told reporters that Iran sought talks only after its military was battered by the US military.

"I think there's a good chance that something could happen," Trump said aboard Air Force One en route to an event in Michigan. "And if it does, good, if it doesn't, we go back to doing what we were doing two days ago."

Trump said that his administration and the Israeli government are "pretty close" to being on the same page regarding Iran.

"We have a little difference, but pretty close," he said of Israeli Prime Minister Benjamin Netanyahu, who is expected to visit the White House on Tuesday.

Trump also reiterated that Iranian assets controlled by the United States will be used to cover damage to ships attacked when transiting the Strait of Hormuz. "We're going to use Iran's money to pay for the damage they did," he said.

Negotiations between Oman and Iran have made progress, though no deal has been reached, according to reports citing regional sources.

Poll: Only 1 in 3 Americans supports war against Iran

Also on Monday, a new poll showed that just one in three Americans supports the war against Iran, the lowest reading since the five-month-old conflict's early days.

The Reuters/Ipsos poll, conducted Friday through Sunday, found that 69 percent of Americans — including four in 10 Republicans -- think US President Donald Trump has not "clearly explained the goals of US military involvement in Iran."

Approval of the conflict has been below 40 percent since the United States and Israel launched joint strikes on Feb 28.
