You’ve probably seen the clips. Maybe it’s the one where a room full of world leaders breaks out in laughter, or the one where he calls a dictator "Rocket Man" from a green marble podium. Honestly, Trump's speech to United Nations sessions over the years became a kind of high-stakes performance art that the world couldn't look away from.
It wasn't just about the words. It was the vibe.
Most people think these speeches were just random outbursts or teleprompter mishaps. They weren't. When you actually dig into the transcripts—from the "totally destroy" warning of 2017 to the "Golden Age" claims of late 2025—there is a very specific, very aggressive blueprint for how he thinks the world should run.
The "America First" Doctrine on a Global Stage
Basically, Trump walked into the home of globalism and told everyone that globalism was dead.
In his 2019 address, he said it flat out: "The future does not belong to globalists. The future belongs to patriots." It’s a wild thing to say to a group of people whose entire jobs depend on international cooperation.
He wasn't just talking to the room, though. He was talking to his base back home.
Sovereignty over everything
For Trump, the nation-state is the only thing that matters. He repeatedly told world leaders that they should be putting their own countries first, just like he was doing for the U.S. This "principled realism," as his team called it, basically threw out the old playbook of "we're all in this together."
Instead, it was more like: "We're all in this for ourselves, and that’s actually okay."

Many diplomats in the room found this terrifying. They argued that issues like climate change or pandemics don't care about borders. But Trump's view? If every country takes care of its own house, the whole world gets cleaner. Or at least, that’s how he sold it.
2017: "Rocket Man" and the Brink of War
The 2017 speech was probably the most shocking. This was his debut.
He didn't ease into it. He took aim at North Korea and Kim Jong Un, calling him "Rocket Man" and saying the U.S. would "totally destroy" the country if forced to defend itself.
- The Shock Factor: Most UN speeches are boring. They are filled with "diplomatese."
- The Reaction: You could hear a literal gasp in the hall.
- The Result: It eventually led to a summit in Singapore, proving that his "insult-first" diplomacy was—at least in his mind—a working strategy.
He also went after Iran, calling the nuclear deal an "embarrassment." He didn't just disagree with it; he loathed it. He saw it as a "one-sided deal" where the U.S. got nothing and the "world's leading state sponsor of terror" got a payday.
The Infamous 2018 Laughter
"In less than two years, my administration has accomplished more than almost any administration in the history of our country."
Trump said that in 2018. The room laughed.
He paused, looked a bit surprised, and said, "I didn't expect that reaction, but that's okay." It’s one of those moments that lives forever on YouTube. But what people forget is that after the laughter died down, he spent the next 30 minutes tearing into OPEC for high oil prices and the International Criminal Court (ICC) for having "no legitimacy."

2020: The "Invisible Enemy" and China
By 2020, the world was a different place. The UNGA was mostly virtual because of the pandemic.
Trump used his time to demand that the UN hold China accountable for "unleashing this plague onto the world." He called COVID-19 the "China Virus" and slammed the World Health Organization (WHO) as being controlled by Beijing.
It was a pivot from the "Rocket Man" days. Now, the big villain wasn't a small rogue state; it was a global superpower. He blamed China not just for the virus, but for dumping plastic into the oceans and overfishing. It was a total grievances list.
The 2025 Return: "Golden Age" and the Green Scam
Fast forward to his 2025 address. This was a "return to form" speech.
He claimed that the U.S. had entered a "Golden Age" and immediately went back to his favorite targets: illegal migration and "green energy." He called climate change policies a "scam" and warned that any country following them would fail.
"If you don't get away from the green energy scam, your country is going to fail." — Donald Trump, UNGA 2025.

He also went after the UN's wallet. He pointed out that the UN was spending hundreds of millions of dollars to "support" migrants moving toward the U.S. border. "The UN is supposed to stop invasions, not promote them," he said. It was a direct threat to UN funding, something he had toyed with during his first term.
The Peace Prize Pitch
By 2025, he was also openly campaigning for a Nobel Peace Prize.
He claimed he had ended "seven un-endable wars" in seven months. Whether that’s factually true depends on how you define "ended" or "war," but the narrative was clear: I'm the peacemaker, and the UN is just a bunch of people who write "strongly worded letters."
Why These Speeches Actually Matter
It's easy to dismiss the rhetoric as just "Trump being Trump."
But there’s a deeper shift happening. His speeches signaled the end of the post-WWII consensus. For decades, the U.S. was the guarantor of global institutions. Trump changed that. He made it clear that the U.S. was no longer interested in being the world's policeman or its piggy bank unless there was a direct, measurable benefit.
Common Misconceptions
- He hates all international groups: Not really. He’s fine with them if they do what he wants or if the U.S. pays less. It's transactional.
- The speeches were improvised: No, they were mostly on teleprompters (even when they broke, like in 2025). They were carefully crafted by "America First" ideologues like Stephen Miller.
- He wanted to leave the UN: He threatened it, sure. But he mostly used the UN as a stage to project power.
Practical Insights for the Future
If you're trying to understand where global politics is headed, you have to look at the "Sovereignty" throughline.
- Watch the money: The U.S. is the UN's largest funder. Trump's speeches aren't just talk; they are budget previews. If he slams an agency (like UNRWA or WHO), expect their funding to vanish.
- Bilateralism is the new black: Don't expect big multi-country deals. Look for one-on-one trade wars or peace treaties.
- The "Nationalist" Trend: Other world leaders are copying this style. From Hungary to parts of South America, the "Patriot over Globalist" rhetoric is a winning political brand.
What you can do next: To get a real sense of the shift, compare Trump’s 2017 "Rocket Man" transcript with his 2025 "Golden Age" address. Notice how the focus moves from "rogue states" to "global institutions." You should also look at the official UN response to his 2025 claims about migration funding—it gives a lot of context on how the "cash assistance" programs actually work.
