SEOUL (AFP): If North Korea uses its nuclear weapons against the United States or its ally South Korea, it would be "the end" of Kim Jong-un's regime, Seoul and Washington announced this week.
The stern threat comes as President Yoon Suk-yeol is on a six-day state visit to the United States, where he and his counterpart Joe Biden discussed ramping up the US security shield for South Korea in the face of the nuclear-armed North's increased missile tests.
