I could give you countless sources documenting US policy that denuclearizes the Korean peninsula. Bush 41 made that call. I am surprised that anyone on this site wouldn't know that.
S. Korea denies seeking redeployment of U.S. tactical nuclear weapons
Well I was in SK in 1991 and the nukes were still there. Article in the Stars and Stripes about them.
I’ve seen em, and they denied they were there then! Would have to believe it is still true to this day. Too much at risk, now even more so!
