John Ferrari and Dillon Prochnicki assess a key challenge for the American military.
The war with Iran is no longer hypothetical. American forces are engaged. Missiles are being launched. Interceptors are being expended. Precision munitions are striking targets across a widening battle space. And with every salvo, one uncomfortable reality becomes clearer: The United States does not look like it can sustain protracted, high-intensity conflict with a near-peer adversary.
This is not a budget debate. It is not an academic exercise in force planning. It is a real-time stress test of the American arsenal, and the early results are troubling. The United States entered this conflict with inventories already strained from years of high operational tempo and insufficient industrial replenishment. Now, as Patriot and Terminal High Altitude Area Defense interceptors are fired to blunt Iranian missile attacks and long-range cruise missiles are launched in sustained strike operations, the depth of America’s magazines is being measured in the only way that ultimately matters, in combat.
Meanwhile, in Beijing and Moscow, analysts are watching closely. Neither China nor Russia needs to fire a shot to learn from this war. They are observing production rates, consumption rates, congressional politics, and the elasticity of the US defense industrial base. They are calculating whether the United States can sustain a prolonged, high-intensity conflict while maintaining deterrence in Europe and the Indo-Pacific. At present, we cannot. War has a way of exposing illusions. One illusion now shattered is the notion that America can rely on small inventories of exquisite, ultra-expensive weapons to carry the day.
This is not the first time the United States has tried to fit its strategy to a shrinking budget and paid for it in blood. After World War II, the Truman administration imposed rigid defense spending ceilings, roughly $10 to $15 billion annually, even as the strategic environment deteriorated sharply. … The military was forced to make do: Units were hollowed out, equipment was deferred, and force structure was cut to fit the fiscal constraints rather than the threat. Strategy became a function of what the budget would allow, not what the world demanded.
