Why Hamas Really Attacked Israel on Oct. 7 | Episode 12
Why Hamas Really Attacked Israel on Oct. 7 | Episode 12 Oct 12, 2026 3205 October 7, 2026, marked the third anniversary of Hamas’s deadly attack on Israel. Considerable attention was devoted to commemorating that event in Israel and throughout the West. The focus was mainly on three questions: 1) What happened that day? 2) Why was Israel caught by surprise? 3) What have been the consequences of that momentous day?  Much less attention was paid to a fundamental question:
We’ll Never Beat the Houthis
We’ll Never Beat the Houthis Oct 9, 2026 640 DESCRIPTIONYouTube Channel member @edhodapp6465 asks: should we go to war against the Houthis, and is damaging Iran's proxies a worthwhile strategy? My answer is no. We're at war with Iran, but we're not fighting the Houthis. They're fighting Saudi Arabia. We already failed to beat them in 2025, and after the war with Iran, we have even fewer munitions now. The Houthis can hit
The Korean War: America vs China | Ask The Professor
The Korean War: America vs China | Ask The Professor Oct 7, 2026 972 YouTube Channel member ⁠@spacecometrue ⁠ asked me to share my analysis of the causes and course of the Korean War. North Korea invaded the South on June 25, 1950, and nearly won before the U.S. stepped in. MacArthur's Inchon landing pushed the North Koreans back to the 38th parallel. When we crossed it and headed for the Yalu River, China entered the war in October 1950, and from that point i
Trump Can’t Bluff Iran into Surrender | Episode 11
Trump Can’t Bluff Iran into Surrender | Episode 11 Oct 5, 2026 2332 DESCRIPTIONIt seems clear that the Trump administration and its allies are working overtime to create the false impression that the United States is well on its way to defeating Iran and that Tehran should therefore submit to American demands sooner rather than later. If it does not, so the argument goes, not only will the economic punishment inflicted on Iran reach crushing levels, but President

The Inescapable US-China Rivalry | Episode 10
The Inescapable US-China Rivalry | Episode 10 Sep 29, 2026 3245 President Trump and President Xi Jinping just concluded a three-day summit in Washington, DC, that was noteworthy for its lofty rhetoric and almost complete lack of progress in dealing with a host of truly important issues: AI, Iran, Taiwan, trade, and Ukraine. The Economist maintains that the two leaders “squandered a chance to tackle the world’s gravest threats,” which it argues “amounts to a de
Is Ukraine Committing National Suicide? | Episode 9
Is Ukraine Committing National Suicide? | Episode 9 Sep 22, 2026 2471 Iuliia Mendel, who served as President Zelensky’s press secretary from 2019 to 2021, published an article in The Spectator on September 15, 2026, titled “Zelensky’s Strategy Is National Suicide.” In essence, she makes a compelling case that Ukraine is not simply losing its war with Russia but is being so thoroughly wrecked in the process that it is effectively committing national suicide. Mendel m

A Must Read Book on the Israel Lobby | Episode 7
A Must Read Book on the Israel Lobby | Episode 7 Sep 8, 2026 2538 Eli Clifton and Ian Lustick have just published a terrific new book called Israel’s Lobby: America in the Grip of a Foreign Power. It appears twenty years after Steve Walt and I published “The Israel Lobby” in The London Review of Books (March 2006), which we turned into a book a year later. Much has happened regarding Israel, the Israel lobby, and the US-Israeli relationship in the two decades si
Why Ukraine Is Doomed | Episode 6
Why Ukraine Is Doomed | Episode 6 Sep 1, 2026 3064 In recent months, Western news coverage of the Ukraine war tells us that Russia is suffering huge casualties on the battlefield while making hardly any progress capturing Ukrainian territory. At the same time, Ukraine’s long-range drone attacks on the Russian homeland are wreaking havoc, which will improve Ukraine’s position at the bargaining table. In short, Russia is in deep trouble and Ukraine’
The False Promise of Tactical Nuclear Weapons | Episode 5
The False Promise of Tactical Nuclear Weapons | Episode 5 Aug 24, 2026 2066 There is considerable evidence that the US is interested in “expanding its options” for using its nuclear arsenal. In particular, it appears that the Pentagon would like to increase its reliance on tactical nuclear weapons for both deterrence and warfighting should deterrence fail. I will argue that fighting a war with tactical nuclear weapons is unlikely to produce a meaningful military victory a
