How Dependent Is the Pentagon on Foreign Suppliers?
The Department of Defense depends on overseas sources for semiconductors, rare earth minerals, and precision machine tools that go into missiles, radar systems, and fighter jets. A 2023 Pentagon supply chain review identified nearly 300 critical product categories where production originates outside the United States. This is not a marginal procurement issue. It is the structural foundation of modern weapons production.
Consider the semiconductor industry. The world's most advanced chips come from Taiwan Semiconductor Manufacturing Company, which produces roughly 90 percent of leading-edge semiconductors. American weapons systems, including the F-35 and naval combat systems, rely on these components. The Government Accountability Office reported in 2024 that the Defense Department lacks full visibility into where many of these chips are made. That means a single shipping disruption, factory shutdown, or political crisis could halt production lines in Texas, Arizona, and Connecticut.
Rare earth elements tell the same story. China processes about 85 percent of global rare earth oxides. These materials go into magnets for guided munitions, electric motors, and satellite systems. The United States once mined and refined these elements at Mountain Pass, California, but decades of low-cost Chinese competition and environmental regulation shifted production abroad. Reversing that trend requires more than executive orders. It demands sustained capital investment and regulatory patience.
Precision machining and specialty metals add another layer. Titanium for aircraft, high-grade steel for submarines, and optical glass for targeting systems often come from allied nations, but not always. A 2024 Commerce Department study noted that domestic capacity for advanced forgings and castings has shrunk by more than half since 1990. The remaining firms are small, aging, and vulnerable to foreign buyouts.
Why Does This Vulnerability Threaten National Security?
Supply chain dependence is not merely an economic risk. It is a strategic liability that adversaries can exploit without firing a shot. China has already shown willingness to restrict exports of gallium, germanium, and graphite when diplomatic relations sour. Those same levers could apply to defense inputs during a crisis over Taiwan or the South China Sea.
Russia's invasion of Ukraine demonstrated how quickly wartime demand can outstrip industrial capacity. NATO allies struggled to produce artillery shells at the rate Ukrainian forces consumed them. The United States sent more than 2 million 155mm rounds from existing stockpiles. Replenishment will take years because only a handful of facilities can make them. If a major conflict erupted in the Pacific, the timeline would be shorter and the demand far larger.
Adversaries do not need to defeat the United States militarily. They only need to delay mobilization long enough to achieve a fait accompli. A blockade, an export ban, or a cyberattack on a foreign supplier could slow American response by months. In a Taiwan scenario, weeks matter. The Navy's shipbuilding plan assumes steady access to foreign machine tools and components. That assumption should frighten anyone who has watched global trade become a weapon.
The economic cost compounds the military one. When suppliers hold pricing power, the Pentagon pays more for less. Cost overruns on ships, aircraft, and satellites partly reflect scarcity premiums hidden in subcontractor invoices. Taxpayers fund the vulnerability twice: once through higher prices and again through reduced readiness.
What Should Congress Do to Rebuild Domestic Capacity?
Congress should treat defense industrial base investment as a long-term capital program, not a yearly appropriations afterthought. That means multi-year funding for rare earth processing, semiconductor fabrication, and advanced forging facilities on American soil. The CHIPS Act of 2022 made a start, but appropriations have moved slowly and permitting remains a bottleneck.
Lawmakers should also reform the Buy American statutes that exist on paper but are riddled with waivers. Too many components labeled domestic originate overseas and receive final assembly in the United States. The Defense Federal Acquisition Regulation Supplement allows waivers when domestic sources are unavailable or too expensive. Those waivers became routine rather than exceptional. Tightening them would force procurement officers to build real alternatives.
Tax and regulatory policy must align with the goal. Mining and refining operations face environmental review timelines measured in years. Some scrutiny is warranted. Endless process is not. Congress should create a streamlined pathway for projects that the Defense Department certifies as critical to national security, while preserving core environmental standards. Speed and stewardship are not mutually exclusive.
Finally, the Pentagon needs better data. You cannot manage what you cannot measure. A classified national supply chain registry, updated annually, would give planners and lawmakers a clear picture of dependencies. The Government Accountability Office has recommended this repeatedly. It is time to fund it.
The Economic Case for Action Now
Rebuilding domestic defense production is expensive, but the alternative is costlier. A nation that cannot arm itself in a crisis loses bargaining power in every other domain. China and Russia understand this. They subsidize their industrial bases openly. The United States pretends market forces alone will solve the problem. They will not.
The federal government spent approximately $886 billion on national defense in fiscal year 2024. A small fraction of that, perhaps 3 to 5 percent, redirected toward supply chain resilience would transform the industrial landscape within a decade. The returns would include jobs in Ohio, Pennsylvania, and Arizona, as well as strategic insurance no foreign supplier can sell.
Conservatives should support this investment without apology. A strong industrial base is a precondition for a strong military. A strong military is a precondition for a stable international order. And a stable international order is the only environment in which American commerce and liberty can flourish.
The Alamo Post was founded this year to argue plainly for such priorities. The defense economy is not a niche concern for contractors and lobbyists. It is the material backbone of American independence. June 3, 2026, is as good a day as any to start treating it that way.
