Is it possible? Yes. But it is possible only when all the nations declare war illegal under all circumstances just as physical abuse is. It is possible when all the nations decide to destroy all the weapons of mass destruction that they have. When an international committee of investigation is set up which has the right to probe into the defense secrets of each nation and certify that it is disarmed of all nuclear and biological weapons and of all weapons of mass destruction. When a nation which possesses weapons of mass weapons or wages wars is punished by cutting off all trade sanctions by all countries. Only then, international nuclear disarmament can be hoped for; not otherwise.
