Pyongyang, North Korea (CNN) -- The Korean Peninsula is a tinderbox. One miscalculation can quickly lead to all-out war and hundreds of thousands of military and civilian casualties on both sides. Millions of North and South Koreans live very close to the DMZ. The North also has a million heavily armed troops on their side of the DMZ; the South nearly has many. There are also nearly 30,000 U.S. troops along the frontier with thousands of artillery pieces and missile launchers facing each other. The North is widely believed to be building a nuclear arsenal. I believe this is the most dangerous spot on Earth right now.

CNN's Wolf Blitzer traveled with Gov. Bill Richardson to communist North Korea

Blitzer was worried war would break out while he was there and would be trapped

Blitzer says he was constantly watched, but his overseers were intelligent, polite

No impression North Korea on the verge of crumbling, Blitzer said
It was a roller coaster of emotions -- ranging from real fear of war on the @placeholder to relief that the North had stepped back from the brink and even accepted some of Richardson's proposals.
