You might not know it, but you interact with space technology countless times on a daily basis. In fact, the space economy has become so ubiquitous that some estimate that its value could reach as high as $1.8 trillion by 2035. On this episode of Next Giant Leap, hosts Mike Massimino and Mike Greenley are joined by Alex MacDonald, former Chief Economist at NASA. They discuss the surprising history of private investment in the space industry, the many reasons for the current boom, and how you might get a job in the space world.

It’s been a banner stretch for President Trump: a major strike on Iran’s nuclear sites, a sprawling tax-and-spending bill pushed through Congress, and a growing foreign policy resume. But beneath the surface of all the flag-waving and victory laps, Democrats like Senator Mark Warner are warning that the real story is unfolding in the shadows—inside an increasingly politicized US intelligence community.

In this episode of the GZERO World podcast, Ian sits down with the senior Senator from Virginia at his Capitol Hill office for a wide-ranging conversation about what’s breaking inside America’s national security institutions—and what that means for foreign policy decisions from Tehran to Gaza. Warner doesn’t hold back: “We’re in uncharted, dangerous territory. [Intelligence] Analysts are being told to change their conclusions—or lose their jobs.”

The two also dive into the fallout from the US-Israeli strikes on Iran, the fragile push for a Gaza ceasefire, and why Warner sees a largely ignored civil war in Sudan as one of the world’s worst ongoing humanitarian crises—and a rare opportunity for the US to lead.

For many of us, the idea of a space-based arm of the military calls to mind images from science fiction. But the real-life world of space defense has become increasingly integral to military operations on land, at sea, and in the air. In this episode of Next Giant Leap, hosts Mike Massimino and Mike Greenley explore the world of space military technology. Guests Major General (Ret.) Kim Crider formerly of the United States Space Force, and Brigadier-General Chris Horner of the Canadian Space Division walk us through the many innovations in this fascinating arena, and attempt to answer one crucial question: how do you secure a domain with no borders?

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.”

Ian Bremmer sits down with New York Times columnist Thomas 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.

For Trump, this marks the biggest foreign policy victory of his second term—at least for now. He struck a blow to Iran’s ambitions, avoided a broader war, and emerged politically unscathed. But what happens next, especially in Gaza, will test the durability of that win.

What if the next virus isn’t natural, but deliberately engineered and used as a weapon? As geopolitical tensions rise and biological threats become more complex, health security and life sciences are emerging as critical pillars of national defense.

In the special edition episode from our new series, “The Ripple Effect: Investing in Life Sciences”, host Dan Riskin is joined by two leading voices at the intersection of biotechnology and defense: Dawn Meyerriecks, former CIA Deputy Director for Science and Technology and current member of the National Security Commission on Emerging Biotechnology, and Jason Kelly, co-founder and CEO of Ginkgo Bioworks. Together, they explore the dual-use nature of biotechnology and the urgent need for international oversight, genetic attribution standards, and robust viral surveillance. From pandemic preparedness and fragile supply chains to AI-driven lab automation and airport biosurveillance, their conversation highlights how life science innovation strengthens national resilience and strategic defense.

This timely conversation follows the June 25th, 2025 Hague Summit Declaration, where NATO allies pledged to invest 5% of GDP in defense by 2035—including up to 1.5% on resilience and innovation to safeguard critical infrastructure, civil preparedness, networks, and the defense industrial base. This limited series, produced by GZERO’s Blue Circle Studios in partnership with Novartis, examines how life science innovation plays a vital role in fulfilling that commitment.

President Trump has never been shy about his revolutionary ambitions. In his second term, he’s moved aggressively to consolidate power within the executive branch—signing more than 150 executive orders in just over 150 days, sidelining Congress, and pressuring the institutions that were designed to check his authority. His supporters call it common sense. Critics call it dangerous. Either way, it’s a fundamental shift in American governance—one that’s unlike anything happening in any other major democracy.

While Congress has largely collapsed into partisan submission, and the DOJ and other power ministries face political purges, one institution still stands: the courts. In this episode, Ian Bremmer speaks with New York Times Magazine staff writer and Yale Law School’s Emily Bazelon about how the judiciary is holding up under pressure, what rulings to watch, and whether the rule of law can survive the Trump revolution.
