Several Senate Republicans this week declined to fully endorse President Donald Trump’s comments that the U.S. had “won” the war in Iran, arguing that there is still more to be done to fully degrade Iran’s capabilities to the extent necessary.

Trump told reporters in the Oval Office Tuesday, “You know, I don’t like to say this — this war has been won. The only one that likes to keep it going is the fake news. … We’ve won this war.” Trump also said Monday he would postpone strikes on Iran’s energy infrastructure to allow for “productive conversations” toward ending the war — an announcement that boosted markets and brought down oil prices.

“I think we’re not done. I don’t like calling it ‘won’ until it’s done,” Sen. James Lankford (R-OK) told Jewish Insider. “You can’t stop a war too soon, once it gets started, because then you’ve got to get right back to it again. You’ve got to finish it.”

Sen. Lindsey Graham (R-SC) said he agreed with the president, but added, “we’ve done a good job of accomplishing our military objectives. We’re not quite there yet.”

Sen. Mike Rounds (R-SD) said, “I think what he means by that — and he happens to be correct — we have basically significantly reduced their ability to wage a lot of the … war. It doesn’t mean they’re not dangerous yet, but we’re getting there.”

Sen. Roger Wicker (R-MS), who chairs the Senate Armed Services Committee, quipped of Trump’s comments, “I think that’s probably hyperbole. It’d be the first time ever, but I think it may be hyperbole.”

House Speaker Mike Johnson (R-LA) hewed more closely to the president’s comments, while stopping short of declaring the war over. “Operation Epic Fury is almost done. I mean, I think the mission that was very clearly defined in the beginning, the objectives have been met,” Johnson told reporters on Wednesday.

Graham, one of the most vocal supporters of the war on Capitol Hill, who has been agitating for the U.S. to pursue full regime change in Iran, said that he would support — and even prefer — a diplomatic outcome.

“Not only do I support @POTUS and his team’s efforts to negotiate with Iran to find a solution to the threats this regime presents to the region and the world, I encourage it,” Graham said on X on Wednesday. “It is the outcome I seek, not the method. I have confidence in President Trump’s negotiating team to make sure that any deal would meet the military objectives laid out early on.”

Those goals, as articulated by Graham, are ending Iran’s ballistic missile program, support for terrorism and nuclear ambitions.

“If diplomacy can achieve these objectives, I would not only support it, but I would also prefer it because war literally is hell,” Graham continued.

Other Republicans are also backing the diplomatic push. Sen. Rick Scott (R-FL) told JI that the president would have better information on the U.S.’ progress toward its goals, but said that from what he has seen, the administration has “made a lot of progress.”

He also expressed support for the administration’s negotiations with Iran about ending the war.

“You always hope war ends,” Scott said. “I hope we’ve fulfilled our mission to destroy their ability to produce nuclear weapons and ballistic missiles.”

“The administration has been very clear that they are about degrading Iran’s missile capabilities, launchers, production facilities, stockpiles, taking out their navy and their nuclear facilities,” Sen. Pete Ricketts (R-NE) told JI. “When they reach a sufficient point, that’s when it’s time to cease the shooting, and hopefully someday the Iranian people will throw off the tyrants that rule them, and we can get a better administration.”
