All the reasons why.
As I have been writing about in recent weeks, the United States and its Asia-Pacific allies have been scrambling to respond to the rapid advances in North Korea’s nuclear program. One idea that has been floated is to redeploy tactical nuclear weapons in South Korea and perhaps even Japan.
To be sure, there have long been lawmakers in South Korea who have been advocating this idea. And, although South Korea’s government continues to oppose such a measure, the idea is been discussed at the highest levels. For instance, South Korean Defense Minister Song Young-moo said that he mentioned to his American counterpart, James Mattis, “that some South Korean lawmakers and media are strongly pushing for [U.S.] tactical nuclear weapons” to be returned to South Korea.
