“A date which will live in infamy” — six carriers strike Pearl Harbor. Tactically brilliant, strategically catastrophic.
THE MOMENT IN CONTEXT
The conflict in Asia began well before the war in Europe. Japan had seized Manchuria in 1931 and launched full-scale war against China in 1937, capturing the coastal cities and the railways, but the Chinese state withdrew inland to Chongqing and fought on. Occupation brought systematic violence against the population, and the Nanjing Massacre included mass murder and sexual violence against civilians and prisoners, which this atlas treats as memorial history rather than as strategy. China’s continued resistance mattered strategically as well as morally, because it tied down a large share of the Japanese army that might otherwise have been used elsewhere.

- The turn — Pearl Harbor, 7 December 1941. Tactically brilliant: eight battleships hit for the loss of 29 aircraft. Strategically self-defeating: the American carriers were at sea, the oil…
- What it changed — The sleeping giant. US industry, one-tenth mobilized, out-produces the entire Axis within a year — by 1944 America launches more ship tonnage every month than Japan…
Then ask the room: Pearl Harbor was one of the most successful surprise attacks in history. Make the case that it was also one of the worst strategic decisions ever made. The argued answer is on the chapter page →
