US Navy acts to control tensions in the Pacific.

S. Korea and Japan have been nose to nose.  China and the Philippines have been nose to nose.  Taiwan and Japan have been nose to nose...and we haven't heard one response from our State Dept.  Instead we have a response from the US Navy in the form of TWO carrier battle groups being sent to the region to calm things down.  Check out this press release from the Commander of the 7th Fleet.
Two of the U.S. Navy's global force aircraft carrier strike groups (CSGs) are currently conducting operations in the vital Asia-Pacific region.
Ships of the forward-deployed George Washington CSG, to include the aircraft carrier USS George Washington (CVN 73), its embarked air wing, Carrier Air Wing (CVW) 5, the guided missile cruiser USS Cowpens (CG 63) and the guided missile destroyer USS McCampbell (DDG 85); coupled with the ships of the John C. Stennis CSG, to include the Bremerton, Wash.-based aircraft carrier USS John C. Stennis (CVN 74), its embarked CVW 9, and the San Diego-based guided-missile cruiser USS Mobile Bay (CG 53); are currently patrolling the Western Pacific. They are providing a combat-ready force that protects and defends the collective maritime interest of the United States and its allies and partners.

The two CSGs are part of a strong U.S. naval presence in the Pacific that has helped to maintain peace and stability in the region as part of the U.S. 7th Fleet, which was established 69 years ago. USS John C. Stennis returned to the 7th Fleet's area of operation four months ahead of schedule to maintain combatant commander requirements for its presence in the region. The crew has been engaging in live-fire exercises, torpedo countermeasures exercises and numerous other training exercises during its current deployment and transit to the U.S. 5th Fleet area of operations.
The issues between these nations stretch back for centuries...in most cases long before the US was even discovered.  Racial, economic and territorial differences make this almost unsolvable.
Conflict will break out.  The best we can hope for is that its contained, and doesn't have longer lasting implications for regional security.  Confidence is not high. Some of the most technologically advanced forces on the planet are nose to nose.  THIS WILL TURN UGLY.
