(WASHINGTON) -- President Donald Trump on Monday claimed the U.S. was "very nearly under threat" from Iran, contradicting U.S. intelligence assessments as he sought to justify his administration's ongoing attack.
"An Iranian regime armed with long-range missiles and nuclear weapons would be an intolerable threat to the Middle East, but also to the American people," Trump said at a medal of honor ceremony at the White House, marking his first public remarks on the military operation.
"Our country itself would be under threat, and it was very nearly under threat," Trump continued.
American intelligence agencies, however, believe Iran would not have had missiles capable of reaching the U.S. for another nine years, until 2035.
And sources confirmed to ABC News that Trump administration officials told congressional staff that U.S. intelligence did not suggest Iran was preparing to launch a preemptive strike against the United States interests.
The officials said there was more of a general threat in the region from Iran's missiles and proxy forces, sources told ABC News.
Still, Trump argued Iran would have "soon" had the capability to reach the American homeland and that "this was our last best chance to strike."
"The regime already had missiles capable of hitting Europe and our bases, both local and overseas, and would soon have had missiles capable of reaching our beautiful America," Trump said.
Trump, in Monday's remarks, laid out U.S. objectives for the military campaign.
"Our objectives are clear," Trump said. "First, we're destroying Iran's missile capabilities, and you see that happening on an hourly basis, and their capacity to produce brand new ones and pretty good ones they make. Second, we're annihilating their navy. We've knocked out already 10 ships. They're at the bottom of the sea. Third, we're ensuring that the world's number one sponsor of terror can never obtain a nuclear weapon ... And finally, we're ensuring that the Iranian regime cannot continue to arm, fund and direct terrorist armies outside of their borders."
Trump notably did not address the issue of regime change after speaking extensively on leadership change over the weekend, as he called for Iranians to rise up and take over the government.
Defense Secretary Pete Hegseth also shifted focus away from regime change in a press conference at the Pentagon earlier Monday, telling reporters the operation was not a "so-called regime-change war."
Ayatollah Ali Khamenei, Iran's supreme leader, was killed in an attack launched by Israel and the United States.
Trump told ABC News Chief Washington Correspondent Jonathan Karl on Sunday that individuals that the U.S. had identified as potential leaders in a post-Khamenei Iran were also dead.
"The attack was so successful it knocked out most of the candidates," Trump told ABC's Karl. "It's not going to be anybody that we were thinking of because they are all dead. Second or third place is dead."
As for what's next, Trump again promised not to drag the U.S. into prolonged foreign conflicts but said the operation will go on for as long as needed.
"We're already substantially ahead of our time projections, but whatever the time is, it's okay. Whatever it takes. We will always, and we have right from the beginning, we projected four to five weeks, but we have capability to go far longer than that. We'll do it."
"Somebody said today, they said, 'Oh, well, the president wants to do it really quickly, after that, he'll get bored.' I don't get bored," Trump added. "There's nothing boring about this."
