Japan Rearms + Guns vs. Butter + Global Defense Spending Boom

As governments around the world ramp up defense spending, a new era of rearmament is reshaping economies, markets, inflation, and politics. This episode examines Japan’s dramatic shift away from its postwar pacifist identity amid rising tensions with China, ongoing conflicts in the Middle East, and growing uncertainty around the global security role of the U.S.

Hosts:

Sebastian Mallaby, Paul A. Volcker Senior Fellow for International Economics, Council on Foreign Relations (CFR)

Rebecca Patterson, Senior Fellow, Council on Foreign Relations (CFR)

We discuss:

• Why the rearmament boom is globally synchronized and big enough to move fiscal balances and bond markets.
• How defense spending is colliding with already massive government debt, and pushing bond yields higher.
• Why Japan’s military transformation marks a significant reversal of its postwar identity.
• Why Japan’s debate over nuclear weapons remains emotionally raw more than eighty years after Nagasaki.
• How fear of China and doubts about the U.S. security umbrella are reshaping politics in Japan and Germany.
• How governments are trying to fund massive military buildups without cutting popular programs, and why bond markets may eventually force a reckoning.
• How rising military spending could fuel another wave of inflation, higher interest rates, and global market volatility, trapping central banks between fighting inflation and financing governments at war.
• As Rebecca Patterson puts it: “All this is happening when governments, frankly, can't afford more guns or butter because debt levels are very high.”
• How AI, drones, and cyberwarfare are rapidly changing the economics and strategy of modern conflict.
• How the new arms race is spilling far beyond the battlefield into tech, energy, supply chains, and the future of globalization.
