Modern Nuclear Weapons
The accuracy of missiles that deliver nuclear warheads has vastly improved during the half-century since the atomic bombing of Nagasaki. At the same time the power of the nuclear warheads has increased enormously while their size has been reduced to facilitate their use in war. Although the number of nuclear weapons has decreased in response to changes in the relationships among nuclear states, there are still tens of thousands remaining in the world. Many difficult problems need to be solved, such as the attitude of the nuclear states that "nuclear weapons are necessary to maintain peace," the expense of dismantling nuclear weapons and the revision of the nuclear industry for peaceful purposes.

Testimonies of the victims of nuclear development and testing are shown on video.
The threat of nuclear weapons is shown by a model of missile and other exhibits.
