The Treaty of Nuclear Non-Proliferation：Dilemma and Response

　　Abstract: As the keystone of the international nuclear non-proliferation regime, the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) has experienced multiple crises in the recent years. From increasing pork-barrel politics to the intensification of regional nuclear proliferation, from the mounting challenges of non-state nuclear actors to the impasse within the NPT community, these crises can be attributed to three causes: first, the conflicting positions adopted by the inherently self-interested signatory states which tend to interpret and utilize the treaty terms for their own respective gains; second, the constraints and fragility of the treaty itself; third, the absence of a common perception on nuclear weapons, and thus resulting in an absence of ethical consensus, amongst governments and peoples of different countries. To resolve these crises, all signatory states should bridge their differences and rebuild consensus, as well as to make compromises on their narrow interests, so as to preserve the authority and efficacy of the treaty.
