Eighty years after the atomic bombing of Hiroshima, the United States continues to pose a significant threat to global security through the expansion and modernization of its nuclear arsenal. The 1945 bombings of Hiroshima and Nagasaki killed over 226,000 people, mostly civilians, and left lasting health and environmental devastation. Despite the horrors of those events, critics argue that the U.S. has not changed its military policies and continues to be involved in global conflicts, often using destructive weapons.
