The return of the nuclear threat, with Admiral James Stavridis
Listen: The world is heading toward a new nuclear arms race—one that’s more chaotic and dangerous than the last. The Cold War built rules of deterrence for a world of dueling superpowers and static arsenals. But in a fragmented, GZERO world of fast-moving technology and unpredictable leadership, the safeguards are fraying. On the GZERO World Podcast, Admiral James Stavridis, former Supreme Allied Commander of NATO, sits down with Ian Bremmer to discuss the growing nuclear threat and what we can do to stop it.
The indicators are alarming: China is stockpiling nuclear warheads at record speed. Russia continues to rattle its nuclear saber in Ukraine. Even US allies are privately and publicly questioning whether they need a deterrent of their own. So how serious is the nuclear risk? How do we guarantee security in a world where the weapons (and the rules) are changing? Are we ready for a future where not just missiles, but lines of code, could end civilization? Stavridis and Bremmer assess the current arms race and what it will take to lower the nuclear temperature.
“We're already involved in a proxy war with a nuclear power,” Stavridis warns, “We'd be smart to try and continue to have strong alliances to balance China and Russia drawing closer and closer together.”
Do nuclear weapons make a country safer?
Does acquiring nuclear weapons make your country safer? It’s a difficult question. On Ian Explains, Ian Bremmer looks back to the 1990s and a tale of two radically different nuclear—Ukraine and North Korea.
Ukraine inherited the world’s third-largest nuclear arsenal after the Soviet collapse. They gave them up in 1994 in exchange for security assurances from the US, UK and Russia. But assurances aren't guarantees, and a decade later, Russia illegally annexed Crimea before launching its full-scale invasion in 2022. Meanwhile, North Korea abandoned diplomacy, pursued nuclear weapons, and lied to the world all along. Now it’s a global pariah, but the uncomfortable truth is nobody’s thinking of invading North Korea. So did Kyiv get played? Did Pyongyang make a smarter move? The contrast between Ukraine’s vulnerability and North Korea’s impunity seems stark. But the story is more complicated. Building nuclear weapons is a gamble, not a strategy. Watch Ian Explains to understand why and what it means for the growing nuclear threat in 2025.

Iran was the clear loser of its war with Israel and the US. So, what happens next?
Less than a month after Iran’s stunning defeat in a brief but consequential war with Israel and the United States, Prime Minister Benjamin Netanyahu has emerged politically stronger—at least for now. But as New York Times columnist Thomas Friedman notes to Ian in the latest episode of GZERO World, that boost may be short-lived unless Bibi finds a credible way to resolve the crisis in Gaza. “The people who won this war for Israel...were, for the most part, the very same people who were in the streets of Israel for nine months against Netanyahu and his judicial coup,” he says. That internal contradiction, he argues, is likely to reassert itself as the conflict continues.
Friedman warns that Netanyahu still faces the same three unappealing choices in Gaza: permanent occupation, rule by local warlords, or a phased withdrawal in partnership with an Arab-led peacekeeping force and the Palestinian Authority. If he were to choose door number three, then Bibi would win the next five elections, Friedman says. But doing so would likely require pressure from Washington. With Trump now touting his foreign policy win in Iran, Friedman believes the moment is ripe for the US to push hard for a ceasefire in Gaza.
The conversation also explores the uncertain road ahead for Iran’s leadership. In the wake of military humiliation, Friedman anticipates an internal debate over whether to double down on nuclear ambitions or seek reintegration into the international community. “All real politics in the Middle East happens the morning after the morning after,” he says. As both Israel and Iran attempt to move forward, Friedman suggests the real reckoning—for governments, publics, and the global order—may just be beginning.

What's next for Iran, with Thomas L. Friedman
Listen: On the latest episode of the GZERO World podcast, Ian Bremmer sits down with New York Times columnist Thomas L. Friedman to dissect what may go down as the most consequential month in the Middle East in years. Just weeks after Israel launched a war against Iran—and after President Trump authorized US airstrikes—an uneasy ceasefire is in place. But what was actually achieved?
Iran, the clear loser of the 12-Day War, entered as the most vulnerable player and emerged weaker still. Tehran stood largely alone, with Hamas degraded, Hezbollah decimated, Syria toppled, and Russia distracted. Yet the Islamic Republic can still claim regime survival, some damage inflicted on Israel, and a murkily intact nuclear program.
Netanyahu, meanwhile, avoided a ceasefire until he had secured key gains: he crippled Iran’s infrastructure, leveraged US firepower to hit targets beyond Israel’s reach, and rescued his collapsing political career. As Friedman notes, “The people who won this war for Israel...were, for the most part, the very same people who were in the streets of Israel for nine months against Netanyahu and his judicial coup.” That tension will only grow in the months ahead.

Attacking Iran has given Bibi new political life. But will he face a backlash at home?
As part of the latest episode of GZERO World with Ian Bremmer, New York Times columnist Tom Friedman breaks down what Israel’s recent military success against Iran means for Prime Minister Benjamin Netanyahu’s political future—and for the ongoing war in Gaza. While Netanyahu appears to be in a stronger position geopolitically and domestically, Friedman warns that the deeper dynamics in Israel haven’t changed as much as they might seem. “The people who won this war for Israel... were, for the most part, the very same people who were in the streets of Israel for nine months against Netanyahu,” he says.
Despite the military gains, Friedman argues that the hard choices about Gaza remain unchanged: partner with an international Arab force and the Palestinian Authority, let local militias take over, or reoccupy Gaza permanently. The first option, he says, would dramatically shift Israel’s regional position: “If Bibi were to choose door number one... he wins the next five elections.” But with Netanyahu’s domestic opposition still raw and ideologically opposed to his vision, Friedman suggests the post-war political chemistry in Israel—and Iran—is about to get “really interesting.”

What Zohran Mamdani’s win really signals for US politics
In this episode of Ian Bremmer’s Quick Take, Ian digs into the surprise Democratic primary victory of Zohran Mamdani in New York’s mayoral race and why it might be “an early signal of something much bigger in the United States.”
Mamdani, a 33-year-old democratic socialist, ran on a platform of $30 minimum wage, state-run groceries, and taxing billionaires. “I don’t think we should have billionaires,” Mamdani told NBC News’ “Meet the Press” on June 29th. Ian unpacks why that kind of economic populism is gaining steam.“
Socialists can’t beat capitalists,” Ian says, “but they can beat kleptocrats.” He warns that both right- and left-wing populism are being fueled by a growing sense that the American system is rigged. As AI begins threatening white-collar jobs, that discontent could spread to entirely new demographics, creating real risk for political and business elites.
“This isn't a mainstream position,” Ian notes. “But it's a hell of a lane for economic populists.”
Will Iran’s regime survive?
What’s next for Iran’s regime? Ian Bremmer says, “It’s much more likely that the supreme leader ends up out, but the military… continues to run the country.” Despite global speculation, real change will depend on the Iranian people, not foreign intervention, says Ian.
As attention shifts to the Middle East, Ukraine faces intensified Russian strikes with less international spotlight. Still, Ian notes NATO support remains “pretty solid,” and the upcoming NATO summit in The Hague will be a key signal of that.
And as China pushes for a multipolar currency system, Ian is skeptical: “It’s not premature to talk about multipolarity economically—it is in terms of a currency order.”
Iran looks to negotiate ceasefire
As the Israel-Iran war intensifies, Iran is seeking an urgent ceasefire, facing overwhelming Israeli military air superiority.
"They have virtually no capacity to strike back,” says Ian Bremmer in today’s Quick Take. Iran has reportedly expended 20% of its ballistic missiles, with minimal damage inflicted, while Israel has crippled large parts of Iran’s military infrastructure and nuclear program.
The US also looms large, as Ian says, “Trump is basically saying, ‘We’re not entering the war, but we will if you don’t engage in negotiations.’” A US-backed strike on Iran’s Fordow Fuel Enrichment Plant remains a real threat if talks stall.
Despite widespread global condemnation of Israeli strikes, even Iran’s allies like Russia are not stepping in militarily. “Regime survival is the priority now,” Ian warns, as internal dissent grows within Iran’s leadership. But with the risk of irrational escalation rising, Ian adds: “That’s the fog of war stuff … far more likely as this war is going on.”
