US Army's 2nd Combat Aviation Brigade, 2nd Infantry Division ROK/U.S. Combined Division conducted combat search and rescue training (CSAR) with the U.S. 7th Air Force

When did the 2nd ID become a combined division? Is it reinforced or is "normal" strength? If we're doing stuff like this then we can pull our guys out. S. Korea, much to the dismay of the "partnership" zealots will NOT participate in a war against China and are focused on N. Korea a bit with the rest of their attention more on Japan. 

Its been tried before, but you just can't build a "NATO of the Pacific". 

 The dynamics of the region just won't allow it.
