The incompetence and mystifying policies of the Clinton administration and the bizarre meddling of Jimmy Carter in 1994 has resulted in a nuclear North Korea. It really is time to leave and let wealthy South Korea and China, who strong vested interests deal with it.
South Korea can handle anything North Korea can throw at them and China isn’t going to allow them to use a nuke against South Korea. In fact I suspect China would crush any further NK research into nukes if we weren’t there.
Its not like we can’t project power if South Korea needs us.
That’s advocating a communist South Korea.
