Lawmakers said on Monday that an additional round of U.S. strikes on Iran remains on the table if the regime makes strides in rebuilding its nuclear program or other malign activities, echoing recent warnings from President Donald Trump.

Trump also threatened last week that the U.S. would intervene to protect Iranian protesters if the regime cracked down on nationwide demonstrations, as U.S. officials are watching closely while Tehran reportedly accelerates efforts to restore its ballistic missile capabilities — developments that could spark renewed conflict with Israel and potentially the United States.

Republican senators expressed confidence that the president would strike Iranian nuclear facilities a second time if the U.S. determined that Tehran was working to restore its nuclear program. 

“I think there’s a chance” Trump will strike Iran’s nuclear sites again, Sen. Rick Scott (R-FL) told Jewish Insider. “If they go forward again and start building up nuclear facilities, yeah, I think Trump’s going to bomb the hell out of them.”

Sen. Pete Ricketts (R-NE) told JI, “President Trump is demonstrating that we have the most outstanding military in the world. And if he believes we have to hit Iran again, I believe he will do that.”

Sen. John Kennedy (R-LA) agreed but dismissed the suggestion that Trump’s willingness to order the operation that deposed Venezuelan President Nicolas Maduro last week signified that the president was looking to resume strikes against Iran. 

“I don’t think one’s related to the other,” Kennedy told JI. “I also think that if Iran starts back in terms of developing a nuclear weapon, or substantially tries to increase the number of missiles that they have, I think the president should hit them and I believe he will.”

Asked about Trump’s threat to intervene to prevent crackdowns on Iranian protesters, and rumors of a potential second round of Israeli strikes on the Islamic Republic, Sen. Richard Blumenthal (D-CT) emphasized the threat of Iran’s missile and nuclear programs.

“We should be considering what action may be appropriate if Iran progresses with its missile building and nuclear programs, which are obviously a pressing and dire threat to us and Israel,” Blumenthal said.

Sen. Tim Kaine (D-VA), a leading voice in the Senate for constraining presidential war powers, who is pushing to block further action in Venezuela, told JI that the U.S. should not be sending in its military in response to the protests, particularly without congressional debate and approval.

“This president should not willy-nilly use the press, use the military as his palace guard to go here, there and everywhere,” Kaine said. “Not Nigeria, not Iran, not Venezuela, not international waters, not Cuba, not Mexico, not Panama, not Greenland. It should be a debate with Congress.”

He added that a constituent, whose son is an Army Ranger, urged Kaine during the holidays to work to prevent unilateral military deployments by the administration. “And I am representing one of the most pro-military states in the country, and that’s what my state thinks,” Kaine explained.
