Nonproliferation Treaty was signed in 1968, and Comprehensive Test Ban Treaty was signed following the Partial Test Ban Treaty. In 1995 Nonproliferation Treaty was extended without date, and other efforts to control the use of nuclear weapons were sustained.
Nuclear security issues recieved attention after the 911 incident in 2001. Nuclear security is the measures taken to stop the threat of nuclear substance and radi-active substances. On January 2007, Kissinger, Perry, Shultz, and Nun who were in charge of US government nuclear related policy insisted on destructing nuclear weapons and coping with nuclear terrorism. They insisted that if nuclear power states do not stop relying on nuclear weapons, it will only stimulate and increase the possibility of nuclear free states to get nuclear weapons. Therefore, they argued that US needs to play a leading role in making the "Nuclear Free World"
Coalition of Nucelar and Terrorism is increasing the worries on the possibility of nuclear terrorism.
As we saw during the 911 incident, terrorists work by hook or by crook, and they do not care about the international nuclear deterrent law because they are hard to repel.
Nuclear Security Summit held in Korea holds many meanings. First of all, it means Korea has followed the nonproliferation system sincerely and the world has acknowledged the fact that Korea has the diplomacy to adjust the different views from all over the world.
Since 2010, Korea actually adjusted different views from the world as the host during the 5 pre-summit and played a leading role to suggest impending matters.
Secondly, Seoul summit suggested a differentiated agenda. They decided to discuss the nuclear power safety issues through nuclear security, discuss radio-active substance terrorism as well as nuclear substance terrorism, turn in mid term self checking report on promises made in Nuclear Security Summit Washington 2010.
Third of all, peaceful use of nuclear power in the Korean Peninsula can be strengthened. Use of nuclear power in the Korean Peninsula is dramatically two-folded. South Korea is using nuclear power peacefully, but North Korea has always been putting great efforts to develop nuclear weapons.
For nuclear free world, efforts should be made from not only the government but also the civil society.
Nuclear Security Symposium and Industry Summit being held with the Nuclear Security Summit Seoul has means a lot. I hope Nuclear Security Summit Seoul becomes an opportunity for Korea to play a leading role in world security.
