Why in HELL would a person do this?

I see on tonight's "news" that Merrill Newman, 85 years old, was released from custody in N. Korea. So let's add this up

You fought behind enemy lines in the Korean conflict, an action surely not to be fondly remembered by your enemy

You are elderly.............85 years old.

So the obvious answer? Why, go "on tour" in one of the most unfriendly countries in the world!!!!!

I have to say, I would not have had a lot of sympathy if the lunatics in N Korea would have kept him.
