The US State Dept home page has declassified documents on the Pueblo Incident.
(See also, http://www.kimsoft.com/2001/pueblo.htm for the ship is now).
What I get from the documents is that the US was in no shape to fight another war (with the Vietnam War simmering).
President G. Bush said last night that North Korea, Itran and Iraq are his next targets. Well, the Korean War isn't over yet.
