Nuclear experimentation is a major global issue that affects relationships between countries. Describe why countries try to limit the testing of nuclear weapons.

Nuclear weapons are weapons of mass destruction. That's why many countries and international organizations are trying to limit its testing: when a nuclear weapon explodes, a lot of energy is released in the form of heat, pressure wave and ionizing radiation. As a result, a nuclear weapon can quickly destroy an entire city and kill hundreds of thousands of people. The radiation causes acute radiation sickness and long-term damage to health.

Because of the enormous destructive power of nuclear bombs, efforts have always been made to abolish all nuclear weapons and to generally ban them in order to prevent them from being destroyed. The Cold War and the power interests of individual nations, however, prevented a rapid abandonment of weapons of mass destruction. Nevertheless, some agreements were implemented, each of which signaled a major step towards a world free of nuclear weapons. However, it is doubted whether the agreements are actually as effective as desired.
