President Donald Trump on Wednesday reiterated his threat to “finish the job” in Iran and said the current ceasefire is “over” while denying that renewed U.S. strikes in the country mark a return to war. 

Trump told reporters during a press conference at the NATO summit in Ankara, Turkey, on Wednesday that he was no longer sure if he was interested in a peace deal with Iran and was questioning if the country’s leadership was rational enough to work with. 

Hours after Trump’s remarks, CENTCOM announced additional strikes on Iranian targets “at the direction of” the president, saying in a statement that the operation was intended to “further degrade [Iran’s] ability to threaten freedom of navigation in the Strait of Hormuz.” 

Asked during the press conference what caused him to sour on Iran’s leadership — whom he referred to on Wednesday as “scum” and “sick people,” after praising them last month as “very rational” and “nice to deal with” — Trump replied: “I got to know them.”

Trump noted that he was comparing the current regime to the previous two regimes in his prior complimentary statements.“I think they’re much more rational than level one, level two. Level one is gone, level two is gone. This is level three,” Trump said. “I think they are more rational, but based on their actions over the last week or two, they’re not doing a service to the people.”

“I’m not sure I want to make a deal with them,” he continued. “We can play games, but I’m not sure I want to make a deal. Let’s just finish the job.”

The comments came hours after the president said that the memorandum of understanding between the U.S. and Iran was “over” and said “I don’t want to deal with them anymore.” 

Trump went on to criticize Iran’s leaders as “a little loco. They’re a little crazy,” pointing to Iran’s continued attacks against commercial shipping in the Strait of Hormuz and claiming he’s Iran’s top target for assassination.

“They want to make a deal, but they don’t know how to make the deal, and then they go around shooting ships at night [in the Strait of Hormuz]. I don’t like that,” he said. “I’m the No. 1 target. … I’m the No. 1, because they’re scum. That’s the way they act, and that’s the way they’ve done it for 47 years.”

Still, he rejected the idea that the military operations meant that the U.S. was resuming full-scale warfare with Iran. 

“I don’t think ​it’s going to start again. I ​think it’s going to go very quickly. They hit a couple of ships, ​and so we hit them ​much harder,” Trump said of the war. “When they hit, we hit. We use their language. We speak their language. No, I don’t think so. I think anything that happens is going to be over very quickly and will only make [the region] safer.”
