Trump Declares ‘America Is Back’ in UN Address, Defends U.S. Power and Presses Iran, Russia

NEW YORK — President Donald Trump took his America First message directly to world leaders Tuesday, using his address before the United Nations General Assembly to defend the exercise of American power, highlight his domestic record and confront some of the most difficult international challenges facing his administration.

Speaking on the opening day of the 81st United Nations General Assembly general debate in New York, Trump began with a declaration intended as much for Americans as for the diplomats sitting before him.

“I can report to you with pride that America is back and our country is stronger today than ever before,” Trump said.

The United Nations confirmed that this year’s general debate opened September 22 and will continue through September 28, bringing heads of state, heads of government and senior officials from around the world to New York.

Trump’s address quickly established its central argument: his administration believes American strength — economic, technological and military — should be used aggressively to address threats rather than allow unresolved crises to continue indefinitely.

He pointed to his administration’s record on the economy, illegal immigration, violent crime and technological development as evidence of what he described as a stronger United States. Trump highlighted stock-market performance, the decline in the official U.S. poverty rate in 2025, reduced illegal crossings at the southern border and lower violent-crime levels in American cities.

But foreign policy soon became the dominant subject.

Trump Defends His Iran Strategy

Iran was at the center of Trump’s address.

The president defended his decision to launch the current U.S. war against Iran, arguing that Washington could not allow Tehran’s nuclear threat to remain unresolved. Trump accused Iranian leaders of repeatedly delaying negotiations and suggested they are now watching the approaching U.S. midterm elections before deciding whether to reach an agreement.

Trump insisted that the November election would not determine his approach toward Tehran.

His message was that decisions involving Iran would be based on what he considers U.S. national-security interests rather than the political consequences for Republicans in November.

The speech came nearly seven months into the current conflict with Iran. The fighting has damaged Iran’s military capabilities and economy but has also contributed to instability in global energy markets and increased tensions throughout the Middle East.

Trump presented his willingness to use force as part of a broader governing philosophy: serious threats, in his view, should not simply be postponed and left for future administrations.

Iran’s delegation responded visibly. Most Iranian representatives seated in the General Assembly walked out as Trump discussed American military operations against Tehran, according to Associated Press reporters inside the chamber.

Despite the confrontation, the possibility of diplomacy has not disappeared.

Secretary of State Marco Rubio said Tuesday that Trump remains willing to meet Iranian President Masoud Pezeshkian while the leaders are in New York, although no such meeting had been scheduled at the time of the statement. Rubio said Trump believes direct engagement can be useful even when the United States and another government remain deeply divided.

Iran has also indicated that diplomacy over the Strait of Hormuz remains possible. Reuters reported Tuesday that an Iranian official said Tehran could reopen the strategic waterway if Washington reduced military pressure and lifted its blockade on Iranian ports.

The competing messages demonstrate the extraordinary stakes surrounding Trump’s UN appearance: military pressure continues, but the diplomatic channel has not been completely closed.

Trump Turns to Russia and Ukraine

Trump also addressed the war between Russia and Ukraine, another conflict that has tested his foreign-policy agenda.

The president said his administration continues working with both Moscow and Kyiv to bring the war to an end and expressed confidence that progress could come more quickly than many expect.

His comments came as Russian and Ukrainian forces continued exchanging long-range attacks. Russia struck several Ukrainian regions overnight before Trump’s UN appearance, while Ukrainian forces hit a Russian oil refinery in Samara. Ukrainian President Volodymyr Zelenskyy was in New York and scheduled to meet Trump during the General Assembly gathering.

Ending the conflict has proved more difficult than Trump predicted during his 2024 presidential campaign. The administration has attempted to broker agreements between the two governments, including efforts to limit attacks on energy infrastructure, but fighting has continued.

Trump nevertheless used the UN stage to make clear that ending the Russia-Ukraine war remains one of his major international objectives.

American Power and the Western Hemisphere

Trump’s address also reflected his administration’s increasingly assertive approach to the Western Hemisphere.

The White House said ahead of the speech that Trump intended to highlight his administration’s strategy for dealing with cartel violence, instability and foreign influence across the region.

His administration has increasingly treated powerful transnational cartels as national-security threats rather than exclusively criminal organizations, while Venezuela has become another major focus of American foreign policy.

Trump was scheduled Tuesday for an informal meeting with Venezuela’s acting President Delcy Rodríguez, an extraordinary diplomatic encounter following the upheaval that removed Nicolás Maduro from power earlier this year. Reuters reported that Trump’s allies say the administration is working with Rodríguez on opening Venezuela’s oil industry to greater U.S. investment, while critics in both parties continue pressing Washington to demand new elections.

The broader message emerging from Trump’s UN appearance was that his administration considers developments throughout the Western Hemisphere directly connected to American economic and national security.

Greenland and Arctic Security

Another major component of Trump’s New York agenda involves Greenland.

The United States, Denmark and Greenland were preparing Tuesday to sign an agreement expanding the American military presence on the strategically important Arctic island. Greenland remains a semiautonomous territory within the Kingdom of Denmark.

Secretary of State Rubio has said the United States should maintain at least two military bases in Greenland, with Arctic missile defense among Washington’s priorities. The agreement is also intended to limit strategic competitors’ ability to gain influence on the island.

The deal follows a long and contentious period in which Trump repeatedly argued that greater American control over Greenland was essential to U.S. security, creating significant tensions with Denmark and other European allies.

Tuesday’s agreement represents a different approach: expanding America’s military footprint while Greenland remains under Danish sovereignty.

Trump Highlights American Technology

Trump also used the speech to emphasize American leadership in advanced technology.

Among the more unusual announcements, the president said he wanted the federal government to begin referring to artificial intelligence as “super intelligence,” arguing that the word “artificial” did not accurately convey the technology’s capabilities.

AP reported that it was not immediately clear whether a formal executive action had been taken to implement the terminology change.

Trump nevertheless presented technological superiority as part of the same national-strength argument underlying much of his address.

The administration has increasingly connected artificial intelligence, advanced manufacturing, military modernization and economic security, portraying technological leadership as essential to maintaining American influence in the decades ahead.

A Different Vision From the UN Leadership

Trump’s emphasis on national power offered a noticeable contrast with the message delivered by United Nations Secretary-General António Guterres.

Guterres called on nations to strengthen international cooperation and argued that the world’s major powers remain interdependent despite deepening geopolitical divisions. He also cautioned against relying exclusively on military power to achieve lasting peace.

Trump approached the same global instability from another direction.

His address emphasized sovereignty, American interests, military capability and the willingness to confront threats directly.

Those policies remain heavily debated. The war with Iran has disrupted energy markets and generated domestic and international opposition, while the Russia-Ukraine conflict remains unresolved despite extensive diplomatic efforts.

Trump’s speech did not retreat from those controversies.

Instead, he used the General Assembly to defend his approach.

A Packed Day of Diplomacy

Trump’s UN appearance was only the beginning of a full day of international meetings.

Reuters reported that the president was expected to meet leaders from four continents, including British Prime Minister Andy Burnham, Ukrainian President Volodymyr Zelenskyy, Venezuela’s Rodríguez, Danish Prime Minister Mette Frederiksen and Greenlandic Prime Minister Jens-Frederik Nielsen.

Trump was also scheduled to meet representatives from Saudi Arabia, the United Arab Emirates, Qatar, Bahrain, Kuwait and Oman, with Iran and broader regional security expected to dominate discussions.

Those meetings reinforce how significantly foreign affairs have come to define Trump’s second term.

From Iran and Ukraine to Venezuela, Greenland and the global competition over emerging technology, the administration is attempting to reshape U.S. relationships with allies and adversaries at the same time.

Tuesday’s United Nations address offered Trump an opportunity to explain that strategy directly to the world.

The message he delivered was unmistakable in its priorities: Trump believes the United States should enter negotiations from a position of strength, protect its sovereignty, maintain technological and military superiority and act when his administration concludes that American security is threatened.

At the United Nations — an institution created around multilateral diplomacy — Trump once again placed American national interests at the center of his case.

For his administration, that remains the defining principle of America First foreign policy.
