What the United States is doing is controlling the physical world's "upstream hard assets"—oil, minerals, shipping lanes, land—using military means; monopolizing the virtual world's "core productivity"—AI computing power, chips, algorithms—using technological means. Then, they make both support each other: using AI virtual dominance to consolidate physical resource dominance; using physical resource dominance to support AI virtual dominance. This creates a global control loop of "dominating the world." This is the true meaning of "cutting off the supply chain"—not just preventing you from producing certain products, but preventing you from entering the next civilization era from the source.
