I saw The Wall Street Journal article today online about how the Nazi SS had forgers counterfeiting British currency and late in the war, dollars. This immediately reminded me of North Korea's ongoing counterfeiting operation with US dollars. The article made the point that in addition to being mass murderers, the Nazis were also common criminals. So North Korea has that in common with the Nazis, too.
So why does anyone expect a regime of gangsters to follow any agreement on a piece of paper ?
