The ongoing — and some would say, worsening — tension between China and Japan over disputed islands in the East China Sea frequently makes headlines.

As the U.S. makes a military and strategic "pivot to Asia," it is entering a highly complex and fluid geopolitical environment.

That's an understatement.
