The atomic bombing of Hiroshima and Nagasaki 78 years ago changed the concept of the impact of wars. The hope that the level of devastation would make the world think seriously about taking steps to give up the arms race and focus on human welfare did not materialise. The arms race continues unabated. From one nuclear weapons state in 1945, the number has increased to nine. Nearly 13000 nuclear weapons present on earth are enough to extinguish humankind. This has raised serious concern among medical professionals resolving to preserve life and promote health, who are now coming together for the complete abolition of nuclear weapons.
