US President Donald Trump said on Sunday that it is “highly unlikely” he will need to order the US back to war with Iran as long as there is progress in negotiations over Tehran’s nuclear program and reopening the Strait of Hormuz.

Axar.az reports that Trump told CNN’s Jim Sciutto during a 20-minute phone interview that it depends on whether Iran signs a very strong agreement.

“The answer is highly unlikely it’s going to be necessary. They’re a failing nation. It just came out, you saw this year, 301% inflation. Highly unlikely it will be necessary. I would if necessary, but we hit them really hard. I hit them so hard. You don’t know how hard I hit them.”

“So it’s highly unlikely I’ll have to,” he continued. “They’re withering away financially. We’ve hit them militarily. We could finish them off.”

The president also said that the US has identified infrastructure targets inside Iran in the event of renewed military action, including power plants and bridges. “We have 38 bridges in our site that we can knock down in literally one hour, “ he said. “They’ll all be down.”

However, he said he would prefer not to destroy Iranian infrastructure. “I don’t want to do that because essentially, it’ll take 10 years to rebuild them,” he said. “I don’t like ripping down bridges. And the hardest thing to build is a bridge. It takes years, and I’m a good builder.”
