Toward a world free of nuclear weapons

The alarming proliferation of nuclear weapons in the world greatly increases the chances of self-destruction. To realize a world without nuclear weapons, leaders and nations of the world must reach consensus.

A promising move in this direction started in the US. The Four Horsemen Henry Kissinger, George Shultz, William Perry and Sam Nunn have twice jointly written articles calling for nuclear disarmament to realize a nuclear weapon-free world. To disarm the nuclear weapon states of their nuclear weapons is an arduous mission that will certainly take a long time, probably decades.

First of all, there must a fundamental change of the mindsets of the Cold War and unilateralism. This seems, for the time being, unrealistic. But complete destruction of nuclear weapons can be achieved through re-adjustment of defense policies and strategies. Leaders of all countries should demonstrate their political will and wisdom for the cause of peace.
