Turkish democracy has come under fresh assault as the Erdoğan government arrested the leader of Turkey's largest opposition party and the mayor of Istanbul, Ekrem İmamoğlu, and issued arrest warrants for more than 100 others. Concurrent with Turkey’s domestic turmoil, Ankara is looking to play a more prominent geopolitical role, both in Syria and in Europe, especially as the US pulls back from the European theater. Soner Çağaptay and Aslı Aydıntasbas join Brussels Sprouts this week to discuss these developments. 

Aslı Aydıntaşbaş is a visiting fellow at the Center on the United States and Europe at Brookings.

The last two decades have marked a revolution in economic warfare. As the United States has increasingly sought to weaponize the global economy against its adversaries, the world has become fractured into competing blocks, resulting in an economic arms race among major powers. This is the argument made by Eddie Fishman in his new book, Chokepoints: American Power in the Age of Economic Warfare. The book tells the story of how the US wielded its economic tools, ranging from sanctions, export controls, investment restrictions, and oil price caps, to address the pressing global security challenges stemming from Iran, Russia, and China. It’s the story of how the world economy became a new frontier of warfare. This week, we’re pleased to welcome Edward Fishman to discuss his new book and how it informs the issues facing us today.

Last month, the Trump administration carried out a large-scale firing of senior military leaders, including the chairman of the Joint Chiefs of Staff, the chief of Naval operations, the vice chief of staff of the Air Force, and the top military lawyers from the Army, Navy, and Air Force. While expected, these moves were nonetheless largely unprecedented, upending longstanding bipartisan and civil-military norms around the continuity of military leadership across political transitions to a new administration.  Kori Schake and Erica Frantz join Andrea Kendall-Taylor and Jim Townsend on this week’s episode to shed light on what the Trump administration’s dismissals of military leaders might mean for the state of U.S. civil-military relations, the health of U.S. democracy, and the conduct of U.S. foreign policy,

This week, the Trump administration announced the suspension of U.S. military aid and intelligence to Ukraine. Reports have emerged that Trump administration officials have held secret discussions with some of Zelensky's political opponents. On Thursday, Trump told reporters he would consider only defending those allies who spend enough on defense. These events, along with everything that has transpired since U.S. Secretary of Defense Hegseth gave his speech to NATO in February, have catalyzed an unprecedented European response as allies are no longer confident that the US will remain a reliable partner moving forward. Allies are ramping up their defense spending; in an emergency meeting in Brussels yesterday, the EU agreed to rearm Europe by mobilizing 800 billion euros in defense spending. This jump in spending is unprecedented for the EU, with 2024 spending hitting a previous record high of 326 billion to rearm. We're very pleased to have Shashank Joshi and Camille Grand on Brussels Sprouts to discuss what all this means.

Last Sunday, Germany held parliamentary elections that are set to usher in a new political era for the country. The far-right Alternative for Germany had its best electoral result ever, capturing 20% of the vote and finishing as the second-largest party in the Bundestag. This domestic shift is taking place against the backdrop of massive turmoil within Europe and the transatlantic relationship, spurred by the Trump administration’s antagonism towards its allies and rapprochement with Russia.  

This episode of Brussels Sprouts, where we analyze Germany’s election results, features Jeff Rathke and James Angelos.

The Trump administration began negotiations with Russian officials in  Saudi Arabia last week, and its exclusion of both Kyiv and its European backers from the table cast doubt on the viability of any potential settlement. At the same time, it is far from certain that the Ukrainians can continue their war efforts without the United States’ support, even if Europe steps up its support in the months ahead. 

This episode of Brussels Sprouts, recorded on the 3rd anniversary of Russia’s full-scale invasion of Ukraine, is joined by Gustav Gressel and Franz-Stephan Gady.

In Munich and Brussels last week, the Trump administration signaled a seismic shift in U.S. policy toward its European allies. Since World War II, the United States has been the primary security guarantor of Europe. Yet recent remarks from President Donald Trump, Vice President J.D. Vance, and Secretary of Defense Pete Hegseth have questioned this status quo.

This week, Brussels Sprouts hosted a special live edition of the podcast, discussing what happens next in the U.S.-Europe relationship with Emma Ashford, senior fellow in the Reimagining U.S. Grand Strategy program at the Stimson Center, and Stephen Wertheim, senior fellow in the American Statecraft Program at the Carnegie Endowment for International Peace.

In recent years, the previous bipolar nuclear order led by the United States and Russia has given way to a more volatile, tripolar one, as China has quantitatively and qualitatively built up its nuclear arsenal. At the same time, there have been significant breakthroughs in artificial intelligence, including for military applications. As a result of these two trends, it is now important to understand and think through the challenges at the AI nuclear nexus, including understanding what our adversaries, China and Russia, are doing in this space. To discuss this and more, Jacob Stokes and Colin Kahl join Andrea Kendall-Taylor and Jim Townsend for a special episode of Brussels Sprouts celebrating the launch of a new CNAS report, Averting AI Armageddon: US-China-Russia Rivalry at the Nexus of Nuclear Weapons and Artificial Intelligence.

Colin Kahl is the Stephen C. Házy senior fellow at the Freeman Spogli Institute for International Studies at Stanford University. During the Biden administration, he served as undersecretary of defense for policy.

The first few weeks of the second Trump administration have seen a flurry of executive orders, tariffs imposed (or threatened) on allies and adversaries alike, and bold statements about world affairs. Trump’s remarks about Greenland, including his refusal to rule out taking the Danish territory by force, have been some of his most provocative and Europe is reeling from this abrupt change in approach. On this week’s episode of Brussels Sprouts, Steve Erlanger and Mij Rahman join Andrea Kendall-Taylor and Jim Townsend to discuss Trump, tariffs, European defense spending, and Ukraine.

For more than 100 years, the continent of Eurasia has played a central role in global geopolitics. In the 20th century, numerous authoritarian powers from Germany under Kaiser Wilhelm II to the Soviet Union aimed for primacy through control of this vast landmass and its resources. Today, command of Eurasia is once again essential to understanding a key geopolitical trend, the intensifying challenge of this axis of upheaval to the Western-led international order. On this week’s episode of Brussels Sprouts, Hal Brands joins Andrea Kendall Taylor and Jim Townsend to discuss all of this and the findings of his new book, The Eurasian Century: Hot Wars, Cold Wars, and the Making of the Modern World.
