With Eliot traveling, Eric welcomes back prolific historian and author Hal Brands to the show to discuss his forthcoming book The Eurasian Century: Hot Wars, Cold Wars, and the Making of the Modern World (New York: W.W. Norton, 2025) which will be published in mid-January. They discuss the ideas and careers of geopolitical thinkers Halford Mackinder, Alfred Thayer Mahan, and Nicholas Spykman whose views about the influence of geography on international affairs became enormously influential among political leaders of all stripes in the early to mid-Twentieth Century. They touch on the costs of deterrence versus the much higher costs of great power wars, the breakdown of the international trading system in the 1930s and how it presaged military conflict, why regional crises in the interwar period rapidly metastasized into the most costly global conflict in history and how our contemporary world resembles the world of 1940-1941. They also discuss the rise of China and the bipartisan consensus it has spawned on diagnosing our current international environment but has not yet led to a bipartisan execution of policies to remedy the situation. They also discuss the rise of geopolitical super predators in the 1930s, the evolution of "Fortress Eurasia" -- the emerging alliance among the PRC, Russia, Iran and North Korea, Senator Mitch McConnell's recent Foreign Affairs article arguing against retrenchment, and why it is hard to imagine a future conflict not becoming a global conflict today.

Shield of the Republic will be taking a break for the holidays and will return in early January.
