Why World War II resources made the Korean War possible

The ability to hold difficult ground in Korea depended partly on the unusually large military inheritance of World War II. Vast artillery stocks supported intensive fire, while numerous ships could provide naval gunfire along the coast. Carrier rotations, aircraft, pilots, and experienced personnel were also still available at a scale that later forces might struggle to reproduce. The point reframes the Korean War as an operation made materially possible by a recent global mobilisation rather than a self-contained post-war campaign.
