Why were Hiroshima and Nagasaki chosen for the atomic bombings? The decision to target Hiroshima and Nagasaki during World War II was based on several strategic factors. Hiroshima, a major military hub, housed important army bases and industrial sites. Its dense urban area promised significant impact. Nagasaki, though not the initial target, was chosen due to its shipbuilding industry and military port. Weather conditions also played a role, as cloud cover over other potential targets redirected the mission. These bombings aimed to force Japan's surrender, ending the war swiftly. The devastating effects on both cities underscored the destructive power of nuclear weapons.
