In his State of the Union address Tuesday night, President Donald Trump maintained his tough talk against Iran, reiterating that he will use force to prevent Iran from getting a nuclear weapon, even though he’s willing to explore diplomatic options to resolve the standoff. 

Trump did not — as some online had predicted — make a grand televised announcement of United States strikes on Iran during the speech. Nor did he elaborate further on his plans for the growing U.S. military might in the region, or what specifically would trigger the U.S. to utilize that military power.

”They want to make a deal, but we haven’t heard those secret words, ‘We will never have a nuclear weapon,’” Trump said about Iran. “My preference is to solve this problem through diplomacy. But one thing is certain, I will never allow the world’s No. 1 sponsor of terror — which they are by far — to have a nuclear weapon. Can’t let that happen.”

A number of moderate House Democrats — around a third of the Democrats in the chamber — as well as the majority of Republicans stood to applaud those comments from the president. Democrats remained largely passive through much of the rest of Trump’s speech.

Negotiations are set to resume between the U.S. and Iran in Geneva later this week.

Trump also insisted again that the U.S. had “obliterated” Iran’s nuclear program in its strikes last June, and had warned the regime in Tehran not to attempt to rebuild its weapons programs, including its nuclear program, but it has continued those efforts anyway.

“As president, I will make peace wherever I can, but I will never hesitate to confront threats to America wherever we must,” Trump said. “And no nation should ever doubt America’s resolve. We have the most powerful military on earth. … It’s really called ‘peace through strength’ and it’s been very, very effective.”

In addition to Iran’s nuclear ambitions, Trump highlighted the Islamic Republic’s manufacture of ballistic missiles, threatening U.S. allies, troops and potentially the U.S. homeland, and its sponsorship of terrorism.

“Since they seized control of that proud nation 47 years ago, the regime and its murderous proxies have spread nothing but terrorism and death and hate,” Trump said. “They’ve killed and maimed thousands of American service members and hundreds of thousands and even millions of people.”

And he again said the regime had killed 32,000 protesters during a recent wave of demonstrations, though he asserted that the U.S. had prevented the regime, through threats of retaliation, from executing “a lot of” dissidents.

Trump boasted of having ended the war between Iran and Israel last year, as well as the war in Gaza, which he said “is proceeding at a very low level — it’s just about there.” Trump offered praise to White House Special Envoy Steve Witkoff and Jared Kushner for their involvement in those negotiations, as well as Secretary of State Marco Rubio.

Rep. Rashida Tlaib (D-MI), who wore a scarf in the pattern of a keffiyeh with a Palestinian flag at its ends, shouted, “It’s a genocide” during those remarks.

Trump also highlighted the successful return of the Israeli hostages: “Believe it or not, Hamas worked along with Israel and they dug and they dug and they dug. It’s tough — it’s a tough thing to do, going through bodies all over, passing up 100 bodies sometimes for each one they found,” the president said.

Trump added that “nobody thought that was possible” to find the remains of the final hostage, Ran Gvili, but Witkoff and Kushner were able to accomplish it.

“I remember the family of the 28th [hostage of the final group that had remained in Gaza]. They were so — grieved, but they were so happy, as happy as it’s possible to be. They had their boy back,” Trump said. He emphasized that the hostage families all wanted to see the remains of deceased hostages come home “as much as though [they] were living.”

Earlier in the day, top congressional leaders received a classified briefing from the administration on Iran, and Democrats emerged urging the administration to explain its position and plans to the American people.

“It’s very serious and the president has an obligation to make his goals public,” Schumer told Jewish Insider after the briefing.
