Nazi revelations stir Germany's post-war ghosts

Lifted from the BBC website, thought some might find this interesting given some of the discussions over the last few days.

Maybe I’m missing something here, but Bolivia doesn’t seem to have been central to (West) German strategic, economic or political considerations in the sixties.

Unless Barbie was the conduit for information about sundry Nazis hiding in South America. But if that was the case, what interest did the Germans have in them? Positive or negative?

Or was German intelligence acting as agent for another power? If so, why?
