Episode 433: Greenland Gambit: Allies, Ambitions, and Arctic Tensions
Today, Martha, Morgan, Amy, and Jess unpack rising tensions in the Arctic following Vice President JD Vance’s visit to Greenland and the fallout in Denmark, among the U.S.’s most reliable allies. This visit was a step too far for many in Denmark: Danish public opinion of the U.S. has plummeted, with over 40% now viewing the U.S. as a threat. Danish officials are now publicly questioning American intentions. As Russia reactivates Arctic bases and China eyes Greenland’s resources, why is the U.S. alienating key allies instead of building strategic cooperation? What does the Trump administration actually want from the Danes, and how does this approach help U.S. national security strategy?Check out the answers to these questions and more in this episode of Fault Lines.Check out the sources that helped shape our Fellows’ discussion: https://www.foxnews.com/video/6370788279112 https://www.npr.org/2025/03/30/nx-s1-5344942/trump-military-force-not-off-the-table-for-greenland#:~:text=Since%201945%2C%20the%20American%20military,with%20some%20200%20soldiers%20today https://www.washingtonpost.com/climate-environment/2025/03/28/greenland-us-bases-history-vance/ https://www.americansecurityproject.org/russian-arctic-military-bases/ https://thedefensepost.com/2023/12/06/russia-arctic-military-presence/ Follow our experts on Twitter: @marthamillerdc@NotTVJessJones @morganlroach@amykmitchellLike what we're doing here?

Episode 432: Pulled Back, Pushed Aside: Stefanik, Power, and Political Trade Offs
Today, Les, Morgan, Martha, and Jess break down the sudden withdrawal of Congresswoman Elise Stefanik’s nomination to be U.S. Ambassador to the United Nations. A key Trump loyalist and early cabinet pick, Stefanik had already sat through confirmation hearings and staffed up at the UN—but with a razor-thin Republican House majority at risk, the administration pulled the plug.What does this move signal about internal GOP priorities and Trump’s personnel strategy? How will the lack of a confirmed U.S. ambassador impact America’s ability to lead at the UN—especially as China and Russia assert more influence? And with Stefanik’s political future uncertain, what’s next for one of Trump’s most visible allies?Check out the answers to these questions and more in this episode of Fault Lines.Check out the sources that helped shape our Fellows’ discussion: https://apnews.com/article/elise-stefanik-united-nations-ambassador-trump-96ef705d7498f080f9f399416b647f99https://www.cnn.com/2025/03/27/politics/stefanik-ambassador-nomination-white-house?cid=ios_app https://www.washingtonpost.com/politics/2025/03/27/elise-stefanik-united-nations-trump/ Follow our experts on Twitter: @lestermunson@marthamillerdc@NotTVJessJones @morganlroachLike what we're doing here?

Episode 431: Signal Gate – Leaks, Leadership, and National Security Risks
Today, Les, Jeffrey, and Jess unpack the fallout from the Atlantic's bombshell report on leaked Signal messages between top national security officials. The controversy erupted when Atlantic editor Jeffrey Goldberg was mistakenly added to the "Houthi PC small group" chat by National Security Advisor Mike Waltz, exposing sensitive national security discussions taking place over unsecured personal devices—including while one official was in Russia. The revelations raise serious concerns about negligence, security breaches, and the erosion of institutional discipline.What does this leak reveal about decision-making at the highest levels? Will U.S. allies lose trust in Washington’s ability to protect intelligence? And with no sign of accountability or investigation, does this signal a larger breakdown in how national security is handled?Check out the answers to these questions and more in this episode of Fault Lines.Check out the sources that helped shape our Fellows’ discussion: https://www.theatlantic.com/politics/archive/2025/03/signal-group-chat-attack-plans-hegseth-goldberg/682176/?gift=0MX4QOJ8hj9Td0f7h7prWQ6KNbodYHBJ3UBWR7do19A&utm_source=copy-link&utm_medium=social&utm_campaign=share https://www.huffpost.com/entry/pete-hegseth-sued-over-signal-text-debacle_n_67e2f9b5e4b074f0c26efadc?nurhttps://www.cbsnews.com/news/trump-envoy-steve-witkoff-signal-text-group-chat-russia-putin/# Follow our experts on Twitter: @lestermunson@NotTVJessJones Like what we're doing here?

Episode 430: Erdoğan’s Power Play: The Arrest of Turkey’s Mayor
Today, Jess, Martha, Les, and Morgan unpack the arrest of Istanbul’s mayor Ekrem Imamoglu —Turkey’s leading opposition figure and the likely challenger to President Erdoğan in 2028. His arrest sparked mass protests across the country and violent clashes, raising alarms over Turkey’s seemingly accelerating democratic backslide.With Turkey’s geopolitical importance, including its strategic role in NATO —will democratic erosion be overlooked for political convenience? Or as Erdoğan tightens his grip, will the Trump Administration speak out for democracy?Check out the answers to these questions and more in this episode of Fault Lines.Check out the sources that helped shape our Fellows’ discussion: https://www.nytimes.com/2025/03/23/world/middleeast/turkey-ekrem-imamoglu-istanbul.html?smid=nytcore-ios-share&referringSource=articleSharehttps://www.nytimes.com/2025/03/22/world/middleeast/turkey-erdogan-democracy-istanbul-mayor-detention.htmlhttps://edition.cnn.com/2025/03/21/middleeast/turkey-protests-erdogan-mayor-intl-latam/index.htmlFollow our experts on Twitter: @lestermunson@marthamillerdc@NotTVJessJones @morganlroachLike what we're doing here?

Episode 429: The Puck Stops Here: Trump, Trade, and Canada’s Political Shift
Today, Les, Morgan, and Andy dive into Canada’s upcoming federal election, expected as early as the end of April. With Liberal leader Mark Carney gaining ground over Conservative Pierre Poilievre, this race could be the first major international political test of the "Trump effect." Trump’s recent trade attacks on Canada—and his unexpected openness to a Liberal government—appear to be reshaping the political landscape.How are tariffs and rising Canadian nationalism impacting the race? Will this lead to more defense spending and deeper cooperation with Europe? And as U.S. support for Ukraine wavers, could Canada step up its military and intelligence leadership on the global stage?Check out the answers to these questions and more in this episode of Fault Lines.Check out the sources that helped shape our Fellows’ discussion: https://www.bbc.com/news/articles/cjw2g88dlqlo https://apnews.com/article/canada-election-mark-carney-trump-tariffs-us-183999b9ec9ca31c200a0d1a0cbbe01b https://www.reuters.com/world/americas/canada-pm-carney-expected-call-snap-election-april-28-globe-mail-reports-2025-03-20/ Follow our experts on Twitter: @AndyKeiser@morganlroach@lestermunsonLike what we're doing here?

Episode 428: Ceasefire or Charade? Breaking Down the Trump-Putin Call
Today, Morgan, Martha, Bishop, and Andrew unpack the high-stakes phone call between Presidents Trump and Putin and what it means for the future of the war in Ukraine. The two leaders reached a limited agreement for a 30-day halt on attacks against Ukraine’s energy infrastructure—but just hours later, both sides launched new strikes.Do we really have an agreement? As negotiations move to Jeddah, is the U.S. making progress toward a real peace settlement, or being drawn into Putin’s playbook? And with Trump backing Putin’s proposal for U.S.-Russia ice hockey matches, is this soft-power diplomacy or a PR win for Moscow?Check out the answers to these questions and more in this episode of Fault Lines.Check out the sources that helped shape our Fellows’ discussion: Follow our experts on Twitter: @BishopGarrison@marthamillerdc@morganlroach@AndrewBoreneLike what we're doing here?

Episode 427: U.S. Strikes on the Houthis – Deterrence or Escalation?
Today, Martha, Les, Morgan, and Jess discuss the latest U.S. strikes on the Houthis in Yemen and whether they will effectively stop further attacks on shipping in the Red Sea. The Houthis, backed by Iran, have been disrupting maritime operations in the region for 17 months—but will this action truly restore deterrence?Is this about targeting the Houthis, or is it really a move against Iran? With Trump designating the Houthis as a terrorist organization and signaling maximum pressure to Tehran, how does this fit into his broader strategy for the Middle East? And, more broadly, as the Houthis continue attacking Western ships while sparing Chinese vessels, where exactly does Beijing stand in this conflict?Check out the answers to these questions and more in this episode of Fault Lines.Check out the sources that helped shape our Fellows’ discussion: https://thehill.com/homenews/administration/5196769-vance-musk-doge-federal-workforce-mistakes/https://www.wsj.com/world/middle-east/in-yemen-strikes-trump-takes-on-a-group-that-has-outlasted-powerful-foes-70ef7b3d?mod=hp_lead_pos8https://abcnews.go.com/International/iranian-general-raises-prospect-response-amid-us-strikes/story?id=119847045Follow our experts on Twitter: @lestermunson@marthamillerdc@NotTVJessJones @morganlroachLike what we're doing here?

Episode 426: Greenland Votes, Trump Provokes
Today, Morgan, Martha, Les, and Jess break down the results of Greenland’s parliamentary elections and what they mean for U.S. strategy in the Arctic. With high voter turnout and the center-right Demokraatit (Democracy) party gaining the largest portion of parliamentary seats, Greenland is navigating a complex path between independence, Denmark, and U.S. influence—just as President Trump openly raises the possibility of annexation.How will Greenland’s new leadership shape relations with the U.S. and Europe? As China and Russia eye Arctic resources, does the U.S. have a real strategy beyond inflammatory rhetoric? And with Denmark frustrated by Trump’s remarks, is the administration undermining NATO just as Arctic security concerns grow?Check out the answers to these questions and more in this episode of Fault Lines.Check out the sources that helped shape our Fellows’ discussion: https://apnews.com/article/greenland-election-demokraatit-trump-arctic-13c295cbc716db2c8011be5819e11fefhttps://www.npr.org/2025/03/13/nx-s1-5325949/greenland-elections-trump-independence https://www.nytimes.com/2025/03/12/world/europe/greenland-election.html?smid=nytcore-ios-share&referringSource=articleShare&sgrp=c&pvid=184EF2B4-0541-43F1-B6F3-E41C7A362BF7 Follow our experts on Twitter: @lestermunson@marthamillerdc@NotTVJessJones @morganlroachLike what we're doing here?

Episode 425: Ceasefire or Stalemate? Ukraine, Russia, and the Trump Factor
Today, Les, Martha, Morgan, and Jess unpack the Ukraine-Russia ceasefire talks brokered in Saudi Arabia, where Crown Prince Mohammed bin Salman has positioned himself as mediator. Ukraine initially pushed for land and sea ceasefires but ultimately backed down, and a key mineral agreement remains unsigned. With Russia still holding out, the ceasefire hasn’t begun — and attacks continue on both sides.Has the Trump administration successfully boxed Ukraine into talks by cutting off intelligence support? What happens if Russia refuses to play along — and will the U.S. actually hold them accountable? Is Zelensky’s return to Trump’s good graces a sign of renewed alignment or deeper dependency? And what does it mean that Europe was left out of the room?Check out the answers to these questions and more in this episode of Fault Lines.Check out the sources that helped shape our Fellows’ discussion: https://www.cbsnews.com/news/ukraine-ceasefire-russia-us-talks-saudi-arabia/https://www.bbc.com/news/live/c51ypekv9xwt Follow our experts on Twitter: @lestermunson@marthamillerdc@NotTVJessJones @morganlroachLike what we're doing here?

Episode 424: Seas of Change? U.S. Strategy in the Indo-Pacific
Today, Jess, Les, Bishop, and Jeffrey discuss rising Indo-Pacific tensions as Chinese warships come within 200 miles of Sydney and conduct live-fire drills near New Zealand. With China’s naval expansion rapidly outpacing the U.S., and American shipbuilding struggling to keep up, concerns are growing over Washington’s AUKUS’ commitments and its broader strategic alliances both in the region and globally.Does the U.S. pivot to a more interest-based foreign policy risk alienating allies? Are China, Russia, and Iran strengthening their partnerships while the U.S. pulls back? And if the U.S. can’t deliver on AUKUS submarine commitments, what does that mean for security in the Pacific?Check out the answers to these questions and more in this episode of Fault Lines.Check out the sources that helped shape our Fellows’ discussion: https://edition.cnn.com/2025/03/06/asia/trump-china-warships-asia-pacific-analysis-hnk-intl/index.htmlhttps://www.newsweek.com/us-news-navy-warship-shiloh-french-polynesia-china-australia-2039709https://www.businessinsider.com/chinas-shipbuilding-power-players-making-warships-at-a-rapid-pace-2024-9 https://www.globaltimes.cn/page/202503/1329755.shtml https://www.theguardian.com/world/2025/mar/07/surface-tension-could-the-promised-aukus-nuclear-submarines-simply-never-be-handed-over-to-australia Follow our experts on Twitter: @lestermunson@NotTVJessJones @BishopGarrisonLike what we're doing here?
