Brussels Sprouts

Over the last two weeks, Russia has repeatedly violated NATO airspace. Seventeen Russian military drones entered Polish airspace on September 10th, followed by another drone in Romania, three Russian jets flew into Estonian airspace for 12 minutes on September 19th, and drones of unknown origin shut down airports in Copenhagen and Oslo on September 22nd. In response to Russia's initial incursion, NATO launched Operation Eastern Sentry to increase and coordinate NATO efforts to counter Russia's drone threat. A new CNAS report released on September 10th details the tactics, techniques and procedures necessary to counter drones and finds current American drone capabilities lacking. NATO's counter-drone capabilities are not sufficient at present and urgent action is needed to prepare NATO militaries to counter Russian drone-based threats. Here to discuss the way forward with us is CNAS's own Dr. Stacy Pettyjohn, who's the co-author of the new CNAS report, and a Brussels Sprouts regular, Michael Kofman. Stacie Pet

Despite the degradation of Moscow’s military in Ukraine, senior western officials estimate that it could reconstitute its forces within two to five years. A new CNAS report considers how a crisis in the Indo-Pacific could shape Russia’s willingness to test NATO. U.S. involvement in a major crisis in Asia would cause Washington to redeploy resources and would-be reinforcements for Europe to the Indo-Pacific, which would create meaningful gaps in NATO defenses. This, in turn, could lead Moscow to perceive a golden opportunity to accomplish its aims: divide the United States and Europe, expand its sphere of influence, and revise the security order in Europe. To discuss the latest Russian provocations and how NATO can fill the gaps in its defenses, we are very fortunate to be joined by General (Ret.) Philip Breedlove and Admiral (Ret.) James Foggo. General (Ret.) Philip Breedlove served as NATO’s Supreme Allied Commander Europe and Commander, U.S. European Command from 2013-2016, capping a 39-year Air Force caree

In the early hours of September 10th, Polish authorities detected 19 Russian drones over Polish airspace. This incident represents a major escalation, with Poland triggering Article 4 of the NATO Treaty. At a minimum, this was an attempt by Russia to get European nations to back down from their support for Ukraine and to expose the Alliance as a paper tiger. The attack also provided the Kremlin with key insights into Poland and NATO's air defenses and its chain of response. So how do we understand what happened and what needs to happen? To answer those very hard questions, we're very fortunate to have Doug Lute and Kurt Volker with us. Ambassador (Ret.) Douglas Lute served as the United States Ambassador to NATO from 2013–2017. Ambassador (Ret.) Kurt Volker served as the United States Ambassador to NATO from 2008–2009 and as the U.S. Special Representative for Ukraine Negotiations from 2017–2019.

This week, we continue our assessment of the Trump-Putin and Trump-Zelensky meetings in August. European leaders can take solace in the fact that their presence at the Washington meeting means that their views are not being entirely ignored, but significant outstanding questions remain relating to how the discussions of western security guarantees for Ukraine could materialize. Now that any appearance of momentum from the meetings has petered out, we take stock of European leaders’ takeaways from the Washington meeting and where Europe goes from here in its efforts to support Ukraine. To share their views on the future of the European security order, we are very happy to welcome Shashank Joshi and Janis Kluge.

The past week has seen a flurry of diplomacy from President Trump as he seeks to bring about a negotiated solution to Russia’s war on Ukraine. While activity has been undeniably high, what fruit has all this effort borne? Sam Charap and Angela Stent join Andrea Kendall-Taylor and Jim Townsend to help make sense of a whirlwind few days and the implications for the future of Ukraine and the transatlantic relationship writ large.

One of the most transformative geopolitical developments in recent years has been the increasing alignment among Russia, China, Iran, and North Korea.  Accelerated by Russia’s invasion of Ukraine, the deepening economic, military, and technological ties among these four countries have resulted in a new Axis of Upheaval—united by shared opposition to a U.S.-led global order. On July 30, CNAS hosted a virtual panel discussing the new report, The Axis of Upheaval: Gauging the Growing Military Cooperation Among Russia, China, Iran, and North Korea. The panel featured: Richard Fontaine, chief executive officer at CNAS Andrea Kendall-Taylor, senior fellow and director of the transatlantic security program at CNAS Karim Sadjadpour, senior fellow at the Carnegie Endowment for International Peace The event was moderated by David McKenzie, director of communications at CNAS Read the report! https://www.cnas.org/publications/reports/the-axis-of-upheaval

Jim and Andrea sit down with Fiona Hill, one of the leading thinkers on Russia, U.S.-Russia relations, and transatlantic affairs. The conversation takes place against a dizzying backdrop of issues, including Russia's escalating attacks on Ukraine and its civilian centers, and political unrest in Ukraine over moves by the Zelensky government to strip anti-corruption agencies of their independence. There are also questions about whether President Trump's 50-day ultimatum to Putin to get to a ceasefire represents a genuine change and a new, harder stance on Russia. Trump was across the pond in the UK over the weekend, and met with European Commission President Ursula von der Leyen to finalize a trade deal with the bloc. But despite reaching a deal, the U.S. forced posture review in Europe, of course, still looms over the future of transatlantic affairs.

During the past several weeks, and since around March of this year, Russia has increased the intensity of its attacks on Ukraine. Moscow is launching brutal aerial assaults on cities and civilian centers, amounting to the largest drone and missile attacks to date in this war. Many eyes are now on Washington as the Trump administration sends inconsistent signals that give onlookers whiplash. Additionally, the bipartisan Senate bill to sanction countries that are still purchasing Russian energy has gained momentum in Congress. But with the August recess fast approaching, it will be a race to get to a vote this month.   To give us an update on the war in Ukraine, we're very pleased to welcome General Ben Hodges and Jana Kobzova.  Ben Hodges is a retired Lieutenant General in the United States Army and the former Commanding General of U.S. Army Europe  Jana Kobzova is the Co-Director of the European Security Programme and the European Council on Foreign Relations  This episode was recorded on July 11, 2025 

In the wake of a very short communiqué and an abbreviated Summit, many questions have been left unanswered by allies. How NATO would manage a reduction of military assets in Europe, support for Ukraine, nuclear strategy, and the rollout of the 5% spending benchmark are all uncertain at the moment, as is the transatlantic relationship.  To help us understand transatlantic dynamics following the Hague Summit, we’re very pleased to welcome Constanze Stelzemüller and Gabrielius Landsbergis   Constanze Stelzemüller is the Director of the Center on the United States and Europe at the Brookings Institution  Gabrielius Landsbergis is the former Foreign Minister of Lithuania  

This week’s episode of Brussels Sprouts is the second part in our series on the future of the New START treaty and the viability of arms control between Russia and the United States. If you haven’t already heard this week’s earlier episode with Frank Miller and Eric Edelman, be sure to give it a listen! In a Foreign Affairs piece from April, one of this week’s guests argues that the U.S. should pursue parallel nuclear arms control negotiations with Russia and China, given the deepening Moscow-Beijing partnership, the U.S. faces the realistic prospect of coordinated nuclear threats or a three-way arms race that could dwarf Cold War tensions. While New START's bilateral framework may be outdated, the piece suggests the window for meaningful arms control hasn't closed entirely—but it requires confronting the new reality of great power competition where America's nuclear rivals are increasingly aligned. This week, Rose Gottemoeller and Jon Wolfsthal join to discuss the future of arms control.   Rose Gottemoeller

On this week’s episode of Brussels Sprouts, we’re kicking off a special 2-part series on the future of the New START treaty and the viability of arms control between Russia and the United States. Tune in now to part 2 to hear the other side of this debate!  In a recent piece in Foreign Affairs, "No New START," this week’s guests argue that in the current geopolitical context, with Russia and China’s increased coordination, military capabilities, and aggression against the West, nuclear arms control only hurts the U.S.’s ability to deter them. With the possibility of conflict in more than one theater, the United States needs to reverse the material constraints put in place by New START in order to curb Russian and Chinese aggression.  So, this week, we’re very pleased to welcome Eric Edelman and Franklin Miller to discuss the U.S.’s future nuclear posture with Russia.  Eric Edelman is a counselor at the Center for Strategic and Budgetary Assessments, and was the Undersecretary of Defense for Policy from 2005-2

Next week, on June 24th and 25th, NATO will hold its annual summit in the Hague. In the run-up to the event, expectations are low among allies. The ultimate goal is to navigate the Summit without major incident and walk away with unity still intact. At the top of the agenda is the historic new pledge to spend 5% of GDP on defense. However, not everything is in agreement going into Tuesday, with varying perspectives on Russia, and Allies anxiously awaiting the outcome of the U.S. posture review to see how a downsized U.S. presence in Europe takes shape.  To discuss expectations and potential outcomes for the NATO Summit, we’re pleased to welcome Julianne Smith and Camille Grand to the podcast.  Julianne Smith is the president of Clarion Strategies and the former U.S. Permanent Representative to NATO  Camille Grand is a Distinguished Policy Fellow at the European Council on Foreign Relations and the former Assistant Secretary General for Defense Investment at NATO 

China has remained a persistent—and increasingly complex—challenge. With looming discussions of tariffs and strategic decoupling from the U.S., European leaders are watching closely: How will Washington’s China policy evolve, and what does that mean for Europe’s strategic posture toward Beijing?  We’re very pleased to welcome Liz Economy and Noah Barkin to help unpack the evolving transatlantic dynamics on China.  Liz Economy is a Principal with WestExec Advisors and a Senior Fellow at Stanford University’s Hoover Institution.  Noah Barkin is a Senior Advisor with Rhodium Group’s China Practice and a Visiting Senior Fellow at the German Marshall Fund 

The relationship between the United States and Europe is facing unprecedented challenges. While the Russian threat to Europe continues to spark fears of a broader conflict, NATO is simultaneously grappling with the implications of a United States that is less committed to European security. To discuss how Europe is reacting to the Trump administration and more, Andrea Kendall-Taylor hosted leading diplomats for a special session at the CNAS 2025 National Security Conference Bogdan Klich, Head of Mission, Embassy of the Republic of Poland The Rt Hon Lord Peter Mandelson, UK Ambassador to the U.S. Jovita Neliupsiene, Ambassador, European Union to the United States Watch the session and more at conference.cnas.org  

Please join the Transatlantic Security Program at CNAS’s Annual Conference: America’s Edge, on June 3rd!  Analysis from the Economist in February this year shows that far-  right parties are now Europe’s most popular family of political parties by   vote share – overtaking conservative and social-democratic parties for the   first time in modern European history.   To help us understand the roots and repercussions of this movement, we’re pleased to welcome Sheri Berman and Richard Youngs.  Sheri Berman is a professor of political science at Barnard College.  Richard Youngs is a senior fellow in the Democracy, Conflict, and Governance Program at Carnegie Europe 

Direct talks between Russia and Ukraine in Istanbul this week – the first since March 2022 – have got off to a shaky start. Putin’s no-show meant President Zelenskyy remained in Ankara on Thursday, but he plans to send a delegation to Istanbul led by his Defense Minister. Russia’s unwillingness to send a more senior delegation suggests they are not taking the talks seriously, and there are few signs they have dropped their maximalist war demands and would be ready to make a settlement with Ukraine that ensures a sustainable peace. With their efforts so far having failed to yield significant results, President Trump has expressed his frustration with both Kyiv and Moscow and personally urged Presidents Putin and Zelenskyy to meet directly.   To discuss this round of talks and the prospects for a peace deal between Russia and Ukraine, we’re very pleased to have Sam Charap and Sergey Radchenko with us on the podcast.     Sam Charap is distinguished chair in Russia and Eurasia Policy and a senior political scient

In highly anticipated federal elections on April 28th, Canada’s Liberal Party emerged victorious after staging a major comeback in the polls over the past several months. This comeback victory took place against the backdrop of rising tensions between Canada and the United States, with the Trump administration’s combative stance toward its northern neighbor having played a role in boosting the popularity of the Liberals. Prime Minister Mark Carney, in his first week, has taken a firm stand against Trump, asserting earlier this week at the White House that Canada was “not for sale.”   To discuss Canada's new political era, Kim Richard Nossal and Elizabeth Anderson analyze the election results and implications for Canadian foreign policy.  Kim Richard Nossal is a professor emeritus in the Department of Political Studies at Queen's University in Kingston, Ontario, and the author of Canada Alone.  Elizabeth Anderson is a Fulbright Scholar and Visiting Associate Fellow in CNAS’s Transatlantic Security Program, as

There’s been a flurry of activity on the Ukraine front this week. Over the weekend, Donald Trump briefly met with Zelensky in Rome during ceremonies for Pope Francis’ funeral. A deal over mineral rights seems imminent, and President Trump rebuked Vladimir Putin, accusing him of leading him along as Russian strikes on Ukraine continue. However, uncertainty over the future of the U.S. and Ukraine continues, especially over whether the U.S. will push Ukraine to accept maximalist Russian demands. This week, Charles Kupchan and Eric Ciaramella join Brussels Sprouts to discuss the status of negotiations over Ukraine and the future of the U.S.–Russia relationship. Charles Kupchan is a senior fellow at the Council on Foreign Relations and professor of international affairs at Georgetown University.  Eric Ciaramella is a senior fellow in the Russia and Eurasia program at the Carnegie Endowment for International Peace.  

On April 9th, Friedrich Merz, the leader of Germany’s center-right Christian Democratic Union, secured a coalition agreement with the Social Democrats following his party’s victory in the federal elections. In early May, the Bundestag is expected to convene and elect him as the next Chancellor. One of the most significant initiatives of this new government is likely to be a historic overhaul of Germany’s defense posture.   To discuss this and more, we’re pleased to welcome Claudia Major and Christian Mölling to discuss Germany's new government and defense strategy.  Claudia Major is the Senior Vice President of Transatlantic Security at the German Marshall Fund Christian Mölling is a Senior Advisor at the European Policy Centre  

Under the Trump administration, U.S. support for Ukraine is no longer guaranteed. President Trump's pause on aid and intelligence to Ukraine in March may have been brief, but it sent a clear message to Europe and Ukraine that the U.S. may no longer be a reliable partner for Ukraine. A reduction or end to U.S. support for Ukraine could have a significant impact on the conflict dynamics in Ukraine and present a challenge for European allies as to whether they can step up and fill the gap.   Celeste Wallander joins the podcast to provide a firsthand account of the evolution of U.S. assistance to Ukraine and to discuss how a united Europe can help Kyiv keep up the fight.  Celeste Wallander was the assistant secretary of defense for International Security Affairs and is a adjunct senior fellow at CNAS.
