The general picture I received from reading Currency Wars, by James Rickards, looks like this:

The world’s trade policies are run by leaders who stand in a circle, each holding a firearm. All of the major players then point their guns at their own heads, screaming, “Stop or I’ll shoot!”

Politicians and media people applaud wildly.

It’s the world leaders who point at others and shoot that we call bad players.

But they all seem nuts to me.
