We Can't Help Saudi Arabia | Ask the Professor
Oct 14, 2026 · 9m
Summary
John Mearsheimer explains that U.S. support for Saudi air defenses fails not due to a lack of will, but because modern offensive missiles and drones overwhelm defensive systems. He cites Israel and Ukraine to illustrate that even with abundant U.S. aid, defenders cannot intercept all incoming attacks. Mearsheimer argues the cost exchange ratio favors attackers, making it impossible for the U.S. to protect Gulf allies or rebuild regional bases against Iran's growing arsenal.
