Mature-node chips (28nm+) are uncontrolled but power 90% of military and infrastructure systems

Export controls focus on cutting-edge chips (sub-14nm, AI accelerators) but leave mature-node chips (28nm and above) completely uncontrolled. These mature chips power 90% of military electronics (radar, communications, guidance systems), automotive controllers, industrial PLCs, and critical infrastructure. China is building massive 28nm fab capacity (60+ fabs under construction) that will undercut global pricing, potentially creating a dependency where Western military systems rely on Chinese-manufactured mature chips. This persists because the export control framework equates 'advanced' with 'strategically important,' ignoring that the most critical systems use older technology, and controlling 28nm chips would disrupt global automotive and industrial supply chains that the economy depends on.
