US President Donald Trump boasted Tuesday of a "turnaround for the ages" in a State of the Union speech, seeking to reverse his dismal polls and see off mounting challenges at home and abroad ahead of crucial midterm elections.
Addressing a joint session of Congress, Trump met repeated standing ovations from Republicans, while Democrats remained seated in protest -- and sometimes heckled.
As US naval and air forces massed in the Middle East, Trump claimed Iran was seeking missiles able to hit US territory but said his "preference" was for a diplomatic solution.
Trump began by painting an optimistic picture, declaring America was "bigger, better, richer and stronger than ever before."
"Tonight, after just one year, I can say with dignity and pride that we have achieved a transformation like no one has ever seen before, and a turnaround for the ages," Trump said.
The 79-year-old hopes the primetime speech, broadcast across all major networks, will help him to sell that message to voters after a deeply divisive first year back in power.
Underwater in opinion polls, Trump fears his Republican Party will lose control over Congress in the November midterms, paralyzing the rest of his second term and exposing him to a possible third impeachment.
He sought to seize on national enthusiasm over Team USA's gold medal winning Olympic ice hockey performance by inviting the players to join him on the floor of the Chamber to massive cheers and chants of "USA."
He then announced he was awarding the Presidential Medal of Freedom -- the highest civilian honor -- to the team's goalie.

US Representative Al Green, Democratic from Texas, exits as he holds a sign reading "Black people aren't apes" as US President Donald Trump delivers the State of the Union address in the House Chamber of the US Capitol in Washington, DC, on February 24, 2026.
And he handed Medals of Honor -- the highest military award -- to a helicopter pilot wounded in January's attack to topple the Venezuelan leader Nicolas Maduro and also to a 100-year-old Korean War veteran.
But at about the hour mark in what became a record-long State of the Union speech, Trump resumed his customary dark rhetoric against opponents and undocumented immigrants.
The New York Times said at least 40 Democratic lawmakers were boycotting the speech.
Iran's 'sinister nuclear ambitions'
Trump claimed that Iran is seeking missiles that could reach the United States and repeated his insistence that the country would never be allowed to build a nuclear weapon.
Iranians, he said, "are at this moment again pursuing their sinister nuclear ambitions."
