President Obama recently extended economic sanctions against North Korea for another year. North Korea is an unusual and extraordinary threat to the national security, foreign policy and economy of not only the US, but also the world. North Korea has weapons-usable nuclear material and is itself a risk of proliferation. North Korea’s envoy to the UN called on the US to lift its economic sanctions against North Korea and urged UN members not to follow Security Council sanctions imposed over the North’s nuclear and missile tests. However, North Korea’s requests are unsound. Without North Korea showing efforts of denuclearization, there is no need for any nation to lift sanctions against North Korea. North Korea over the past years have betrayed the trust of the international community by acting on their words. Without signs of advancement in North Korea, the sanctions will stand firm.
