The DPRK has set itself the goal of becoming the most powerful nuclear and military power, the Permanent Representative of the Republic to the UN, Cha Son Nam. Speaking at a meeting of the UN Security Council on North Korea on December 15, he stressed that Pyongyang, regardless of anyone's statements, will go ahead, and "triumphantly progress as the most powerful nuclear and military power". "It is obvious to everyone that the DPRK does not violate the interests of other countries," Cha Son Nama quoted RIA Novosti as saying.. The Permanent Representative added that his country's nuclear weapons serve only for self-defense and security in the region. Earlier it was reported that US Senator Lindsay Graham said that the administration of President Donald Trump is likely to start a war with North Korea against North Korea if Pyongyang conducts another nuclear test.
