The Iran War Has Exposed Gaps in US Weapons Stockpiles as Washington Presses Southeast Asia on Deterrence

Five months of fighting with Iran have drawn down American munitions faster than industry can replace them, and Al Jazeera has posed the question directly: where did the money go if the United States, after years of historically large defence budgets, is running short of interceptors and precision weapons. The gap between appropriated spending and delivered inventory is the central fact, and it is not disputed by either critics or supporters of that spending.

At the same time, Washington is asking its partners to take on more responsibility. Pentagon policy chief Elbridge Colby told a forum in Manila that the United States wants Southeast Asian states to join a strategy he called flexible realism, prioritising practical defence cooperation and hard deterrence over ideological alignment. Viewed alongside America's depleted stockpiles, the request is partly an industrial one: allied purchases and allied production capacity substitute for American inventory that Washington no longer has to spare.

An analysis grounded in Austrian economics, which distinguishes real production capacity from the amount of money spent, is uncomfortable for both political camps here. Large, sustained appropriations do not automatically produce capacity when the money flows through a procurement system with few suppliers, long lead times and cost-plus contracting. Capital gets committed to programmes rather than to actual output, and the shortfall only becomes visible when a real war consumes real ammunition.

That is why the current cycle should outlast the Iran conflict. Replenishing interceptor and artillery stocks takes years of production, and every ally now asked to hold more of its own inventory adds to the same order book.
