Whenever there is a global crisis, natural disaster or manmade, civilians or of a security related issue - the world turns their eyes to the United States of America.

The indispensable nation. The only global super-power. You all know the drill.

Is it an honor, or a burden? Is it a habit we should, or can sustain?

Our guest for the full hour to discuss this and related issues will be Christopher Preble, vice president for defense and foreign policy studies at the Cato Institute.

As a starting point for our discussion, we will use the article he co-authored with William Ruger at War on the Rocks, No More of the Same: the Problem with Primacy.
