The United States is deploying a "nuclear triad" at the borders of North Korea. Next week, Virginia submarines may appear on the border zone of the two Koreas.
Washington is taking these measures in light of the growing threat from North Korea, Yonhap news agency reports, citing a source in Seoul. The United States may also send an aircraft carrier to North Korea to have the vessel involved in joint military drills with South Korea in March.
North Korea's recent nuclear tests raised serious concerns in the White House. To demonstrate its military power, the US sent B-52 bombers to the region. After Pyongyang launched a space satellite, South Korea and the United States admitted the deployment of elements of the US missile defense system on the Korean Peninsula.
