Some scary stats on China's militaro-industrail complex's capacity: - China casts more metal products than the next nine countries combined and >5× the US. - Its shipbuilding capacity is ~200× the US (a total-capacity figure, not per-ship speed). - It makes ~90% of the world's commercial drones, and controls ~80% of drone components. - Chinese civilian factories could retool within a year to produce ~1 billion weaponized drones annually using under 1% of existing assembly capacity.
