US arms rebuild hinges on China amid gallium bottleneck

The Middle East conflict has damaged U.S. radar interceptors in the region, depleting stocks and forcing Washington to restock. A key bottleneck is gallium, a critical mineral largely processed in China, which could give Beijing leverage as the U.S. seeks to rebuild its weapons cache. Gallium prices have surged and experts warn diversifying and securing resilient supply chains will take years, prompting the U.S. to pursue allied deals (e.g., with Australia), stockpiles, and domestic refining capacity to reduce dependence on China.
