Brent Johnson (Milkshakes, Markets and Madness) hosts his friend John Butler for a friendly-but-probing debate on whether US military involvement in Iran is a geopolitical master class or a historic mistake. Both agree there is a plan, the situation is tragic, and the GCC’s free-rider arrangement with the US is ending—but they diverge sharply on who benefits most: Johnson argues the United States is best insulated relatively (Western Hemisphere focus, Venezuela oil secured, can weaponize chaos), while Butler argues Russia emerges as the clear winner due to land power, Caspian trade with Iran, and the US failing to pursue offshore balancing. Both agree a scorched-earth US policy in the Gulf would plunge the world including China into a decade-long depression.

The free-rider arrangement is ending: The Gulf’s post-WWII “free rider” model of US-guaranteed security in exchange for rents is no longer sustainable as Iran, backed by Russia and China, directly challenges the arrangement. Butler sees this regional transition as inevitable regardless of short-term military outcomes, with Iran playing the long game via Russian/Chinese support.
Declining empires love sowing chaos: Johnson’s key argument is that if Iran can use a drone to shut down Hormuz indefinitely, so can the US—and with Venezuelan oil taken off the board, North America and Russia relatively benefit from Gulf disruption while everyone else suffers. Butler agrees declining hegemons rely disproportionately on military power because “it’s affordable” but warns this accelerates imperial decline like late-19th-century Britain in India.
Nuclear proliferation calculus: Butler argues the more the US plays heavy-handed, the more likely Russia and China eventually hand Iran a bomb as a “Merry Christmas” gift just to get the US off their back. Johnson pushes back that no country has successfully become nuclear when the US was actively trying to stop them (except Pakistan), and this strike has lowered Iran’s odds, not raised them.
Russia as the disproportionate winner: Butler’s core thesis is that Russia benefits most because of land-power geography, decades of strategic planning, Caspian Sea trade links to Iran, and the ability to fill Europe’s energy void. Johnson concedes Russia is well-insulated but argues the US is equally or better positioned given Western Hemisphere focus and its ability to project sea power to deny others access.
Global depression is the base case if scorched-earth plays out: Both agree closing Hormuz for a sustained period throws the entire world—including the US—into depression, because Russia’s current infrastructure cannot fill the Gulf’s void for 10-20 years. Butler predicts this would reorder European governments, force China into isolationism drawing on cultural memory of hardship, and potentially leave Iran as the eventual regional Persian Gulf hegemon once the artificial Gulf states collapse without their sugar daddy.
