Episode 504: Probes and Provocations: Russia Tests Estonia – and NATO
Today, Les, Jamil, Andy, and Jess unpack a dangerous new escalation on NATO’s flank: three Russian MiG-31s flew through Estonian airspace for several minutes on Friday, a violation Tallinn says it can prove even as Moscow denies the incident and accuses Estonia of provocation. NATO jets — including Italian F-35s and fighters from Sweden and Finland — scrambled in response. The incursion follows recent Russian drone overflights of Poland and Romania and comes amid an uptick in attacks inside Ukraine, raising alarms across Europe about Moscow’s willingness to push boundaries.How should the U.S. and NATO respond to airspace violations that creep toward Article 5 thresholds? Is the right answer a sharper military posture — more weapons and patrols for Ukraine and Baltic defenses — or tighter economic and diplomatic pressure? And with allies in Europe calling for stronger action, will Washington elevate its response or risk encouraging further Russian probing?Check out these sources which informed our experts’ opinions: https://apnews.com/article/british-intelligence-mi6-russia-war-443df0c37ff2254fcc33d5425e3beaa6 @lestermunson@NotTVJessJones@jamil_n_jaffer@andykeiserLike what we're doing here?

Episode 503: Pageantry or Progress? Trump’s UK State Visit
Today, Morgan, Bishop, and Marc break down President Trump’s second state visit to the United Kingdom. The visit featured the largest military honor guard ever assembled for such an occasion, alongside announcements of major U.S. private-sector investments in UK industry from Microsoft, Nvidia, Palantir, and others. Was this visit a substantive step forward in the U.S.-UK “special relationship,” or more pageantry than progress? How significant are the tech partnerships and investment pledges for the UK’s economy—and what do they signal about AI and tech regulation going forward? With many of the agreements still “aspirational,” how much weight should we give to this moment of symbolism and transatlantic continuity?Check out these sources which informed our experts’ opinions: https://apnews.com/article/trump-uk-state-visit-starmer-chequers-bc9088873ab7fc481c7163d60fe4da98https://www.foxnews.com/world/trump-invokes-churchill-special-relationship-questions-over-uk-free-speech-grow https://www.npr.org/2025/09/18/nx-s1-5544343/trump-starmer-press-conference@morganlroach@bishopgarrison@WashingtonFlackLike what we're doing here?

Episode 500: Defining the Next Era of National Security
To mark Fault Lines’ 500th episode, Martha, Jamil, Les, Morgan, and Jess reflect on how September 11, 2001 reshaped U.S. national security—and what comes next. From the trauma of that day to more recent shocks like political violence at home, the team examines how terrorism has evolved but remains a persistent threat, both domestically and abroad. They share personal experiences from 9/11 and the years that followed, the unity it inspired, and the lessons Americans cannot afford to forget.But if terrorism once defined an era, what will define the next? Will it be great power competition, a resurgent Russia, technology-driven threats, or growing disunity at home? How can the U.S. strike the balance between strength and restraint, maintain deterrence without complacency, and rebuild trust in American leadership at home and abroad?@morganlroach@marthamillerdc@NotTVJessJones@jamil_n_jaffer@lestermunsonLike what we're doing here?

Episode 499: Operation Summit of Fire: Israel Strikes in Doha
Today, Morgan, Martha, and Bishop break down Israel’s dramatic strike on Hamas officials in Doha, part of Operation Summit of Fire. The attack killed five Hamas leaders—including the son of senior figure Khalil al-Hayya, though al-Hayya himself survived—and has sparked outrage in Qatar, a key U.S. partner and major host of CENTCOM operations. The Trump administration reportedly received little advance notice, raising questions about coordination and accountability.What does this escalation mean for Israel’s war in Gaza and the broader Middle East? Does striking so openly in a U.S. ally’s capital mark a dangerous new precedent—or simply reinforce the longstanding message that those who threaten Israel will be hunted down? How will this affect hostage negotiations, U.S.–Qatar relations, and the fragile path toward a potential ceasefire?Check out these sources that helped shape our experts’ opinions: https://apnews.com/article/qatar-explosion-doha-e319dd51b170161372442831a8023db5 @morganlroach@marthamillerdc@bishopgarrisonLike what we're doing here?

Episode 498: Russia’s Biggest Strike Yet—What’s Next for Ukraine and the U.S.?
Today, Martha, Morgan, and Jess discuss Russia’s most massive aerial strike since the start of the full-scale invasion—an onslaught of over 800 Shahed drones, plus ballistic and cruise missiles. For the first time, Moscow hit Ukraine’s Cabinet of Ministers building, alongside devastating strikes on civilian areas. President Trump, signaling frustration, pledged to speak with Vladimir Putin soon as his team weighs a “phase two” sanctions package targeting Russian oil revenues and potentially punishing foreign buyers. Despite summits and talk of diplomacy, there is still no ceasefire framework or serious negotiations in sight.What does Russia’s choice of targets reveal about its strategy at this stage of the war? How effective could a new round of U.S. and European sanctions be in pressuring Moscow? And with no diplomatic momentum, what options remain for Washington and Kyiv to shift the trajectory of the conflict?Check out these sources that helped shape our experts’ opinions: https://www.politico.com/news/2025/09/02/congress-pulls-the-rug-on-u-s-plan-to-beat-huawei-00527620https://www.nytimes.com/2025/09/04/world/asia/china-hack-salt-typhoon.html?smid=nytcore-ios-share&referringSource=articleSharehttps://www.washingtonpost.com/national-security/2025/05/23/cisa-cyberattacks-china-doge-cuts/ @marthamillerdc@morganlroach@NotTVJessJonesLike what we're doing here?

Episode 497: Salt Typhoon — China’s Cyber Blitz
Today, Jess, Martha, Morgan, and Algene break down Salt Typhoon — a years-long Chinese cyber campaign that impacted 80 countries, targeted U.S. telecommunications firms, and compromised millions of people, including political leaders and even National Guard systems. A new multinational report links the operation to three Chinese firms tied to Beijing’s military services, underscoring the scale of China’s push to dominate the global cyber domain even as the U.S. cuts cyber budgets.How much damage did Salt Typhoon really do, and why should Americans care? Will Congress step up to strengthen U.S. cyber defenses? And why is Washington pulling back at the very moment that Beijing is doubling down on cyber operations?Check out these sources that helped shape our experts’ opinions: https://www.politico.com/news/2025/09/02/congress-pulls-the-rug-on-u-s-plan-to-beat-huawei-00527620https://www.nytimes.com/2025/09/04/world/asia/china-hack-salt-typhoon.html?smid=nytcore-ios-share&referringSource=articleSharehttps://www.washingtonpost.com/national-security/2025/05/23/cisa-cyberattacks-china-doge-cuts/ @marthamillerdc@morganlroach@NotTVJessJones@AlgeneSajeryLike what we're doing here?

Episode 496: FAFO Doctrine: Israel’s Strike on the Houthis
Today, Les, Martha, Morgan, and Jess break down Israel’s strike on senior Houthi leaders in Yemen—a dramatic escalation in the conflict that has seen the Houthis effectively declare war on the Red Sea. Despite a U.S.-backed ceasefire in May, the group has continued to fire on international shipping, crippling global trade routes through the Suez Canal and acting as a key proxy for Iran. Israel’s strike, which killed the Houthis’ prime minister, foreign minister, and senior advisers, signals a shift in tempo and a warning shot at Tehran’s allies.Does this change the long-term balance in the Red Sea, or will the Houthis adapt and keep attacking? How much leverage do Israel and the U.S. really have, given the Houthis’ resilience against years of outside strikes? And with Israel adopting what officials call the “FAFO doctrine”—short for “f— around and find out”—are we entering a new phase of deterrence?Check out these sources that helped shape our experts’ opinions: https://www.bbc.com/news/articles/c620ykrxedwo https://www.reuters.com/world/middle-east/thousands-attend-funeral-houthi-leaders-killed-by-israeli-strike-vow-revenge-2025-09-01/ https://www.wsj.com/world/middle-east/israel-hit-yemen-targets-just-hours-after-intelligence-officers-flagged-an-imminent-houthi-meeting-2eb3dd81 @LesterMunson@marthamillerdc@morganlroach@NotTVJessJonesLike what we're doing here?
