Fault Lines

Today, Morgan, Les, Andrew, and Amy unpack Israeli Prime Minister Benjamin Netanyahu’s visit to Washington, where he is set to meet with President Trump to discuss the ongoing U.S. negotiations with Iran. Netanyahu intends to ensure Israeli security interests are addressed and to share intelligence as Washington continues talks with Tehran. While the Trump administration pursues diplomacy, it has also deployed U.S. carriers to the region, signaling that negotiations are backed by force. The administration has made clear its core demands are full denuclearization and an end to the regime’s violent repression of protesters. But with Iran weakened, boxed in, and facing deep internal unrest, would its regime rather endure U.S. pressure than accept terms that could threaten their grip on power? As both leaders weigh the risks of escalation today, can they shape an outcome that prevents a nuclear Iran without triggering a broader regional conflict?Check out the answers to these questions and more in this episode of Fault Lines.@lestermunson@morganlroach@amykmitchell@AndrewBoreneLike what we're doing here? Be sure to rate, review, and subscribe. And don't forget to follow @faultlines_pod and @masonnatsec on Twitter!We are also on YouTube, and watch today's episode here: https://youtu.be/-6IvHW_uTVY Hosted on Acast.

Today, Les, Jamil, and Jess break down Japanese Prime Minister Sanae Takaichi’s sweeping victory in a snap election, a historic result that gives the Liberal Democratic Party a two-thirds majority in the lower house for the first time since World War II. The outcome dramatically strengthens Takaichi’s political mandate and opens the door to significant shifts in Japan’s national security policy. With a strong working relationship with Washington, the moment may be ripe for deeper U.S.–Japan coordination and a stronger coalition to counter China’s growing military power, including its rapidly expanding nuclear arsenal.While Takaichi now has the authority to act on national security issues, economic concerns are what drove voters to the polls. Can she deliver economic results while advancing a more assertive defense agenda? And as China pushes regional red lines, how will Japan balance domestic pressures with the strategic realities ahead?Check out the answers to these questions and more in this episode of Fault Lines.@lestermunson@jamil_n_jaffer@NotTVJessJonesLike what we're doing here? Be sure to rate, review, and subscribe. And don't forget to follow @faultlines_pod and @masonnatsec on Twitter!We are also on YouTube, and watch today's episode here: https://youtu.be/BAf34HsixlI Hosted on Acast.

Today Jess, Les, Morgan, and Matt unpack the expiration of New START, the 2010 arms control treaty long described as the last remaining guardrail on U.S. and Russian nuclear forces.  Washington and Moscow together hold roughly 85% of the world’s nuclear weapons but Russia has proven an inconsistent arms control partner, raising questions of what, if anything, comes next. Is negotiating a new agreement worthwhile if Russia and China show little interest in being constrained?  What would a credible next framework need to include? And absent a formal treaty, what informal mechanism can realistically prevent a new arms race?@morganlroach@lestermunson@NotTVJessJones@WMattHaydenLike what we're doing here? Be sure to rate, review, and subscribe. And don't forget to follow @faultlines_pod and @masonnatsec on Twitter!We are also on YouTube, and watch today's episode here: https://youtu.be/SzqhtbLQ1EQ Hosted on Acast.

Today, Morgan, Jamil, Les, and Andy survey a busy week in the Western Hemisphere, as the Trump administration sharpens its focus closer to home. President Gustavo Petro’s visit to the White House signaled a thaw in U.S.–Colombia relations, with renewed counternarcotics cooperation and discussions around exporting Venezuelan natural gas to Colombia. Meanwhile, Panama’s Supreme Court annulled a contract allowing a Hong Kong–based company to operate ports at the Panama Canal, prompting sharp warnings from Beijing and aligning closely with Washington’s push to limit China’s influence in the region.Are these signs that the U.S. is finally reasserting itself in the Western Hemisphere? Is the message landing with China and Russia as Washington draws firmer lines around the Panama Canal, Venezuela, and regional security? And after years of U.S. neglect that allowed Beijing to become a top trading partner for many Latin American countries, can renewed attention actually push adversaries out and deliver lasting influence?Check out these sources that shaped our Fellows’ discussion: https://www.reuters.com/world/asia-pacific/china-calls-panama-court-ruling-ck-hutchison-port-contracts-shameful-pathetic-2026-02-03/https://www.nbcnews.com/politics/white-house/trump-meet-colombian-president-gustavo-petro-venezuela-nicolas-maduro-rcna257101 @morganlroach@jamil_n_jaffer@lestermunson@andykeiserLike what we're doing here? Be sure to rate, review, and subscribe. And don't forget to follow @faultlines_pod and @masonnatsec on Twitter!We are also on YouTube, and watch today's episode here: https://youtu.be/m8I6GmEM9pI Hosted on Acast.

Today, Les, Jamil, Morgan, and Matt turn to Sudan, where a brutal civil war has entered its third year and now stands as one of the world’s worst humanitarian catastrophes. As fighting between the Sudanese Armed Forces and the Rapid Support Forces continues to displace millions and drive staggering civilian casualties, regional powers are deepening their involvement. With Turkey, Egypt, the UAE, and others backing opposing sides, the conflict is increasingly shaped by proxy warfare and emerging military technologies.What does this escalating proxy fight mean for U.S. interests? As Washington pulls back traditional aid tools and shifts its foreign policy posture toward trade and economic leverage, does the U.S. still have influence in a conflict this severe? How should policymakers think about Sudan’s strategic geography, especially as China and Russia look for openings to expand their footprint? And in a war where outside actors fuel the violence but Sudanese leaders bear responsibility, what role, if any, should the United States play?Check out these sources that shaped our Fellows’ discussion: https://www.msn.com/en-us/politics/general/sudan-humanitarian-situation-is-worst-crisis-of-2025/ar-AA1SIQ00?ocid=BingNewsVerphttps://abcnews.go.com/International/wireStory/sudans-war-torn-capital-sees-commercial-flight-land-129749973 https://www.nytimes.com/2026/02/01/world/africa/egypt-sudan-drones.html @morganlroach@jamil_n_jaffer@NotTVJessJones@WMattHaydenLike what we're doing here? Be sure to rate, review, and subscribe. And don't forget to follow @faultlines_pod and @masonnatsec on Twitter!We are also on YouTube, and watch today's episode here: https://youtu.be/V-2AvosoABM Hosted on Acast.

Fault Lines Episode 551: Between Rhetoric and Reality: What’s Going on in IranToday, Morgan, Jamil, Matt, and Jess take a closer look at Iran, where widespread unrest continues largely out of view. Reports suggest protests have erupted in hundreds of cities, with tens of thousands killed or detained as the regime has tightened control, shut down the internet, and doubled down on its support for the Ayatollah. As Europe moves to designate the IRGC as a terrorist organization and U.S. naval forces operate nearby, President Trump has issued stark warnings, calling on Tehran to end its nuclear ambitions and stop killing protesters, while hinting at behind-the-scenes contact with Iranian interlocutors.What happens now? Is this another wave of protests destined to be crushed without meaningful international support, or is there a real window for outside pressure to make a difference? What does Trump mean when he says “help is coming,” and does credibility suffer if that help never materializes? Is the United States prepared to act, or content to wait and see yet again?@morganlroach@jamil_n_jaffer@NotTVJessJones@WMattHaydenLike what we're doing here? Be sure to rate, review, and subscribe. And don't forget to follow @faultlines_pod and @masonnatsec on Twitter!We are also on YouTube, and watch today's episode here: https://youtu.be/YgxnXBFULCc Hosted on Acast.

Today, Jess, Les, Morgan, Andrew, and Amy break down the National Defense Strategy released last Friday, the Pentagon’s core blueprint for deterring adversaries and preventing conflict. Issued just weeks after the White House rolled out its National Security Strategy, the NDS reinforces familiar themes: deterring China through strength rather than conflict, pushing allies and partners to shoulder more regional security burdens, prioritizing the Western Hemisphere, and revitalizing the U.S. defense industrial base. Does the strategy signal a meaningful pivot toward de-escalation with China? Can U.S. allies and partners realistically fulfill the burden-sharing roles the strategy assigns them? And as sovereignty, trade, and security increasingly collide, does this strategy provide a clear framework for managing overlapping global threats—or allow for too much ambiguity at a critical moment?@NotTVJessJones@lestermunson@morganlroach@AndrewBorene@amykmitchellLike what we're doing here? Be sure to rate, review, and subscribe. And don't forget to follow @faultlines_pod and @masonnatsec on Twitter!We are also on YouTube, and watch today's episode here: https://youtu.be/Z1HdVjwfpvM Hosted on Acast.

Today, Les, Jamil, and Matt discuss the removal of General Zhang Youxia, one of the most senior figures in China’s military. Zheng’s ouster, amid allegations of corruption and possible espionage, marks the latest in a sweeping series of purges that many say have hollowed out China’s top military leadership, leaving Xi and just one other general at the apex of the Central Military Commission. As Xi appears to position himself for an unprecedented fourth term in 2027, the shakeup raises new questions about stability inside the Chinese Communist Party and the People’s Liberation Army.Is Xi consolidating power or has paranoia begun to consume his own system? Do these purges weaken China’s ability to act militarily, particularly toward Taiwan, or do they increase the risk of miscalculation? And as Beijing continues aggressive exercises, cyber operations, and coordination with Russia, how should the United States interpret this moment? @jamil_n_jaffer@lestermunson@WMattHaydenLike what we're doing here? Be sure to rate, review, and subscribe. And don't forget to follow @faultlines_pod and @masonnatsec on Twitter!We are also on YouTube, and watch today's episode here: https://youtu.be/k9_kzrJSN3s Hosted on Acast.

Today, Morgan, Les, Matthew, and Jess discuss the latest diplomatic push around Ukraine, following a flurry of high-level meetings at Davos and beyond. President Trump and President Zelensky met for more than an hour as the World Economic Forum wrapped up, while Jared Kushner and Steve Witkoff traveled to Russia to meet with Vladimir Putin. For the first time since the war began, American, Ukrainian, and Russian officials are now slated to meet face-to-face in Abu Dhabi to discuss military and security issues, raising questions about whether momentum toward a negotiated settlement is finally building.But are we actually any closer to peace? What would it take for Putin to seriously engage, given his repeated rejection of past proposals and the political risks he faces at home? Is Trump’s increasingly tough rhetoric a signal of leverage, hinting at greater military support for Ukraine if diplomacy fails, or a strategy to give Putin a face-saving off-ramp? @morganlroach@lestermunson@WMattHayden@NotTVJessJonesLike what we're doing here? Be sure to rate, review, and subscribe. And don't forget to follow @faultlines_pod and @masonnatsec on Twitter!We are also on YouTube, and watch today's episode here: https://youtu.be/HA-taYy4ero Hosted on Acast.

Today, Les, Jamil, Morgan, and Jess discuss Greenland as President Trump arrives at the World Economic Forum in Davos and once again places the Arctic island at the center of global attention. While Trump’s rhetoric has sparked backlash across Europe, the debate raises serious strategic questions: Greenland’s growing importance to U.S. national security, its role in Arctic defense, and why Washington has sought greater influence over the territory for more than a century.Should we be wringing our hands or rending our garments over the Kerfuffle with Europe? Does the United States have a legitimate national security interest in Greenland, and if so, what’s the right way to pursue it without fracturing NATO unity? How should Washington balance pressure with reassurance to allies already rattled by the war in Ukraine? And as Trump enters his second year in office, what does the Greenland debate tell us about how this administration plans to wield power going forward?@lestermunson@jamil_n_jaffer@morganlroach@NotTVJessJonesLike what we're doing here? Be sure to rate, review, and subscribe. And don't forget to follow @faultlines_pod and @masonnatsec on Twitter!We are also on YouTube, and watch today's episode here: https://youtu.be/RTw7qRU1Z6U Hosted on Acast.

Today, Jess, Les, Andrew, and Joshua take a step back from the headlines for a Fun Friday roundtable on the best and worst American foreign policy decisions, inspired by a recent Council on Foreign Relations article drawing on conversations with the Society for Historians of American Foreign Relations. From the Marshall Plan and Bretton Woods to PEPFAR and the peaceful end of the Cold War in Europe, the team reflects on moments when U.S. leadership, economic power, and long-term thinking paid real dividends.What separates foreign policy successes from failures? Why do some hard-power decisions look effective at first but unravel over time? And as the U.S. looks ahead, what should decision-makers keep firmly in mind before reaching for any one instrument of power?Check out the article that helped shape our Fellows’ discussion: https://www.cfr.org/ten-best-ten-worst-us-foreign-policy-decisions/?utm_source=newsrelease&utm_campaign=best-worst-2026&utm_medium=email&utm_term=PressCFR%20-%20Including%20Members%20and%20Staff @NotTVJessJones@lestermunson@AndrewBorene@joshuachuminskiLike what we're doing here? Be sure to rate, review, and subscribe. And don't forget to follow @faultlines_pod and @masonnatsec on Twitter!We are also on YouTube, and watch today's episode here: https://youtu.be/FR_W1-fpr5o Hosted on Acast.

Today, Les, Jamil, Morgan, and Andy revisit Iran as protests continue to escalate and the reported death toll climbs into the thousands. President Trump was briefed this week on response options and has publicly signaled support for demonstrators, saying that “help is on the way.” What does meaningful support for Iranian protesters actually look like? Should the United States openly back regime change—and if so, how, given limited military presence and a fractured opposition? Are covert action, cyber operations, and coordination with regional partners more realistic tools than overt force? And as Trump isolates Iran economically and diplomatically, is this the beginning of a pressure campaign that could genuinely tip the balance, or another moment of outrage without follow-through?@lestermunson@jamil_n_jaffer@morganlroach@andykeiserLike what we're doing here? Be sure to rate, review, and subscribe. And don't forget to follow @faultlines_pod and @masonnatsec on Twitter!We are also on YouTube, and watch today's episode here: https://youtu.be/bVOL-Ec7zB0 Hosted on Acast.

Today, Les, Jamil, Morgan, and Jess discuss escalating protests across Iran, where economic collapse and political repression are driving nationwide unrest. Demonstrations that began with small business owners have spread to major cities, prompting a violent crackdown by security forces and an internet shutdown. As the regime insists the situation is under control, President Trump has warned publicly that continued mass killings could trigger U.S. action, while Iranian officials have quietly floated the possibility of renewed nuclear talks.Is this protest movement meaningfully different from past uprisings that fizzled under pressure? Has the regime been weakened enough, internally and externally, for unrest to threaten its hold on power? And with Iran’s opposition fractured and no clear alternative government waiting in the wings, what leverage does the United States actually have if it wants to support change without creating a far more dangerous vacuum?@lestermunson@jamil_n_jaffer@morganlroach@NotTVJessJonesLike what we're doing here? Be sure to rate, review, and subscribe. And don't forget to follow @faultlines_pod and @masonnatsec on Twitter!We are also on YouTube, and watch today's episode here: https://youtu.be/wS56YpITIdI Hosted on Acast.

Today, Jess, Les, Morgan, and Matthew discuss why Greenland has suddenly become a focal point of U.S. foreign policy. President Trump has reignited debate by publicly suggesting the United States should own Greenland, escalating rhetoric well beyond existing basing rights under the 1951 agreement with Denmark. While administration officials have walked back any suggestion of force, Greenlandic leaders have rejected the idea outright—even as the island’s strategic importance grows amid heightened Arctic competition involving Russia and China.What national security concerns is the administration trying to address with its approach to Greenland? Is the focus on Greenland driven by concerns over Russian and Chinese military activity, access to critical minerals, missile overflight risks, or all of the above? And while the U.S. case for Greenland’s strategic importance is clear, does the administration’s approach risk alienating Denmark and other NATO allies — and if so, at what cost to Arctic cooperation?@morganlroach@lestermunson@NotTVJessJonesLike what we're doing here? Be sure to rate, review, and subscribe. And don't forget to follow @faultlines_pod and @masonnatsec on Twitter!We are also on YouTube, and watch today's episode here: https://youtu.be/65o2FCiBrjw Hosted on Acast.

Today, Morgan, Les, Jamil, and Algene discuss the United States’ announcement that it would provide security guarantees to Ukraine as part of a potential peace settlement with Russia. The move follows discussions in Paris between U.S. and European partners, outlining a proposed security architecture for Ukraine and “legally binding” commitments meant to support a postwar order. U.S. Envoy Steve Witkoff and Jared Kushner have both indicated President Trump’s backing, and Ukrainian officials say roughly 90 percent of a peace framework is agreed—though major territorial questions remain unresolved.What do security guarantees actually mean in practice, and do they bring Ukraine any closer to a durable peace? Are these commitments meaningful deterrents, or largely symbolic without clear enforcement mechanisms? And with Russia showing no willingness to accept a ceasefire—or the presence of Western peacekeepers—what happens if Moscow simply ignores the framework altogether? Check out the sources that helped shape our Fellows’ discussion: @morganlroach@lestermunson@jamil_n_jaffer@algenesajeryLike what we're doing here? Be sure to rate, review, and subscribe. And don't forget to follow @faultlines_pod and @masonnatsec on Twitter!

Episode 541: Operation Maximum Resolve - Regime Tailoring?Today, Les, Morgan, Jess, and Matthew discuss the U.S. operation in Venezuela over the weekend that extracted President Nicolás Maduro and his wife and brought them to New York to face drug trafficking charges. While the Trump administration says no U.S. troops are currently on the ground and denies plans to run Venezuela’s day-to-day affairs, the operation follows months of apparent intelligence and military preparation and coincides with a significant U.S. naval presence offshore. Former Vice President Delcy Rodríguez has been sworn in as interim president, setting the stage for a highly uncertain next phase inside the country.Is this regime change—or a more limited leadership removal designed to avoid the mistakes of past U.S. interventions? Does extracting a single leader offer a cheaper, more effective alternative to invasion and occupation, or does it raise serious questions about sovereignty and international law? And can the United States translate a stunning military and intelligence success into lasting deterrence, democratic opportunity, and a rollback of Russian and Chinese influence in the Western Hemisphere?@lestermunson@morganlroach@nottvjessjonesLike what we're doing here? Be sure to rate, review, and subscribe. And don't forget to follow @faultlines_pod and @masonnatsec on Twitter!We are also on YouTube, and watch today's episode here: https://youtu.be/OEyq3qnwbyo  Hosted on Acast.

Episode 540: The Holiday Special - Unwrapping 2025Today, Jessica, Jamil, Morgan, Lester, Les, Lipsey, Matthew, and Marc take stock of a consequential year in U.S. national security. From President Trump’s push to brand himself as a “peace president”—highlighted by multiple diplomatic agreements and the Gaza peace plan—to moments of hard power, including U.S. and Israeli strikes on Iran’s nuclear program, 2025 defied easy labels. The team reflects on undercovered but significant developments as well: the dismantling of the U.S. foreign assistance architecture, growing concern over advanced technology transfers to China, sweeping changes to the federal workforce through DOGE, and a renewed focus on the Western Hemisphere, particularly Venezuela and Haiti.Looking ahead to 2026, what will ultimately shape U.S. national security: the trajectory of Ukraine, a recalibration of China policy, or the domestic pressures of a midterm election year? Are tariffs becoming a permanent tool of U.S. leverage or a temporary negotiating tactic? And as the administration continues to reshape how American power is exercised, which lessons from 2025 will matter most?@jamil_n_jaffer@nottvjessjones@lestermunson@WashingtonFlack@morganlroachLike what we're doing here? Be sure to rate, review, and subscribe. And don't forget to follow @faultlines_pod and @masonnatsec on Twitter!

Episode 539: Live from RNDF: Ambassador YuiAs part of our crossover series of Fault Lines and CTRL+F, “Modern Deterrence: Allies, Innovation, and the Future of Defense,” recorded live at the Reagan National Defense Forum, Jess and Jamil sit down with Ambassador Yui, Taiwan’s Representative to the United States. With more than 35 years of diplomatic experience—including senior leadership roles in Taiwan’s Ministry of Foreign Affairs and postings across Europe, Latin America, and the U.S.—Ambassador Yui offers a uniquely informed view of the shifting security landscape in the Indo-Pacific and Taiwan’s evolving role within it.How does Taiwan assess the current deterrence environment amid intensifying PLA activity and hybrid pressure from Beijing? Where are the biggest opportunities, and remaining obstacles, in United States–Taiwan defense, economic, and technological partnership? And as Taiwan advances major modernization efforts, from asymmetric defense to cyber resilience and semiconductor security, what should Washington understand about the capabilities, priorities, and challenges shaping Taiwan’s strategic future?@jamil_n_jaffer@nottvjessjonesLike what we're doing here? Be sure to rate, review, and subscribe. And don't forget to follow @faultlines_pod and @masonnatsec on Twitter!

As part of our crossover series of Fault Lines and CTRL+F, “Modern Deterrence: Allies, Innovation, and the Future of Defense,” recorded live at the Reagan National Defense Forum, Jess and Jamil sit down with Washington Harbour Partners Founder and Chief Investment Officer Mina Faltas - with a surprise appearance from NSI Advisory Board Member and Silverado Policy Accelerator co-founder Dmitri Alperovitch. Together, they explore how private capital, technological innovation, and strategic competition are reshaping the future of American and allied deterrence. How are investors evaluating risk in an era defined by U.S.–China rivalry, hybrid conflict, and accelerating breakthroughs in technology? What role should private capital play in national security, and where is the market still mispricing geopolitical and regulatory risk? And as cyber and space become more central to modern conflict, how can the U.S. and its allies strengthen resilience and build the next generation of deterrence?@NotTVJessJones@jamil_n_jafferLike what we're doing here? Be sure to rate, review, and subscribe. And don't forget to follow @faultlines_pod and @masonnatsec on Twitter!We are also on YouTube, and watch today's episode here: https://youtu.be/pPe4xGxqF2w Hosted on Acast.
