Common misconceptions
  • Treating atomic bombings as solely 'ended the war' — refuses single-perspective framing per Vietnamese-own-voice + decolonial-own-voice promises; hibakusha-own-voice is required per MG-14d
  • Treating the decision as unanimous — Szilard petition + Franck Report + Eisenhower + Leahy expressed reservations
  • Conflating Hiroshima with Nagasaki — distinct cities, distinct weapons, distinct death tolls; both deserve naming
