North KoreaÂ’s neighbors bolstered their military preparations and mobilized scientists Wednesday to determine whether PyongyangÂ’s third nuclear test, conducted in defiance of U.N. warnings, was as successful as the North claimed.
The detonation was also the focus of global diplomatic maneuvers, with U.S. Secretary of State John Kerry reaching out to counterparts in Seoul, Beijing and Tokyo. President Barack Obama used his State of the Union address to assure U.S. allies in the region and warn of “firm action.” |
