Q&A Petrov & Beattie / US-UN-Nokor / On Monday, the United States warned of further consequences should North Korea make good on its threat to conduct another nuclear test. South Korea's U.N. ambassador, Kim Sook, told reporters a nuclear test appears to be imminent and promised a swift U.N. Security Council response. The U.S./based website 38 North says Pyongyang's nuclear site is in a high state of readiness to conduct another nuclear test. North Korea has threatened to conduct its third nuclear test and carry out more rocket launches in retaliation for a tightening of U.N. Security Council sanctions against Pyongyang over its December rocket launch. Some analysts say North Korea's provocative behavior is a warning to South Korea's incoming administration not to continue its current tough policy against the North. Leonid Petrov, Korea researcher at the Australian National University, tells VOA's Victor Beattie the North sees its nuclear program as part of the Korean conflict, which only ended in an armistice in 1953.
