US President Donald Trump said he was less confident that Iran will agree to stop uranium enrichment in a nuclear deal with Washington.

Axar.az reports, citing Reuters, “I don’t know,” Trump told the “Pod Force One” podcast on Monday when asked if he thought he could get Iran to agree to shut down its nuclear program. “I don’t know. I did think so, and I’m getting more and more — less confident about it.”

In the podcast interview, Trump said Iranians seem to be using delaying tactics.

“I’m less confident now than I would have been a couple of months ago. Something happened to them, but I am much less confident of a deal being made,” he said.

Trump repeated that the US would not allow Iran to have a nuclear weapon, whether or not a deal is reached.

“But it would be nicer to do it without warfare, without people dying, it’s so much nicer to do it. But I don’t think I see the same level of enthusiasm for them to make a deal,” he said.
