It has become an important issue since the Iranian nuclear facilities were found by the US satellite in December 2002. The issue involves energy, regional security, credibility of international organization and Nuclear Non-Proliferation Treaty. Therefore, it provokes various opinions in international society. Based on NPT, there is no doubt that Iran has rights of using nuclear technology peacefully. On the other hand, it is unacceptable for European Union (EU) and International Atomic Energy Agency (IAEA) that if Iran tries to develop nuclear weapon by stealth.
Iran strongly insists on the rights of developing nuclear technology. It attracts international concerns that how EU deals with Iran in this issue by means of diplomacy, let alone the result. After the Iraq war, the US government realized that their Middle East policy was blocked in dilemma. Although the US government still claims that they will solve this problem by force, it is obvious that the US government, in some respects, needs EU to intervene in this issue. Hence EU plays an important role in settling this international issue.
Not only EU, but also Iran, the US, and other states, such as Russia, China and Israel, take important parts in this issue. It is worth observing whether these states agree with the way that EU deals with this problem. In this issue, there is no highest authority in international society. Although IAEA is in charge of the use of nuclear technology and NPT, the situation of nuclear proliferation is not well-controlled. Therefore, the law and order of NPT needs to be seriously reviewed and criticized.
