    The Korean War: America vs China | Ask The Professor

    07/10/2026 | 16 mins.
    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 it was really a war between the U.S. and China. It ended in an armistice in July 1953, not a peace agreement. I also explain why each side fought. North Korea wanted to unify the peninsula. The U.S. came in after Dean Acheson's blunder, because a Soviet ally controlling Korea threatened Japan and Northeast Asia. China found U.S. troops on its border unacceptable, much as Russia saw Ukraine in NATO. I also cover how the war militarized the Cold War, and why I think the Korean Peninsula is stable today despite North Korea's nuclear weapons. ————————————————————

    Episode 11: Trump Can’t Bluff Iran into Surrender

    06/10/2026 | 38 mins.
    DESCRIPTION

    It 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 Trump will launch a devastating military attack that might even include putting U.S. ground forces into Iran. I will argue in this episode that this is largely a propaganda campaign—and that it is unlikely to work because Iran, not the Trump administration, is in the driver’s seat.

    Episode 10: The Inescapable US-China Rivalry

    29/09/2026 | 54 mins.
    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 dereliction of duty, and leaves the rest of humanity as the losers.” I disagree. I will review what happened at the summit regarding each of these issues and explain why, with the possible exception of trade, the underlying conflicts of interest between China and the United States leave little room for meaningful agreement.
