It's like living on a heavily populated barrier island during hurricane season - if you wait to get off until you're sure of the hit, you won't get off at all...

Except in this analogy, if you try to leave the barrier island enmasse, you may hasten the arrival of said hurricane.

As one geopolitical wonk has put it - “North Korea is the land of lousy options”.
