(FOX NEWS) — President Donald Trump said Wednesday the U.S. could make a “good deal” with Iran now, but warned that a military option could produce a “great deal” that would be “nastier” but “foolproof.”

“I can say that, we can make a good deal right now, but maybe not a great deal,” Trump said at Wednesday’s monthly Cabinet meeting at the White House, when asked whether an Iran deal could be tied to more countries joining the Abraham Accords.

Trump said he would not disclose what is or is not contingent in the negotiations, but suggested the U.S. still has stronger options if diplomacy fails.

“If it’s not a great deal when I’m making it, because we can make a great deal with this guy right here,” Trump said, pointing to his left at War Secretary Pete Hegseth. “It’s a lot nastier. Probably wouldn’t go as quickly … but it would be foolproof.”

Trump said negotiations are going “pretty well,” but again criticized the Obama-era Iran nuclear deal as “the worst deal” and “a path for Iran to have a nuclear weapon very quickly.”

The president also said the U.S. did not set out to pursue regime change in Iran, but argued that recent losses had effectively transformed Tehran’s negotiating team.

“We didn’t set out for regime change,” Trump said. “But by the fact that we’re dealing with a totally different group of people than we were at the beginning … This is regime change.”
