Reuters reports that “the balance of military power in the Asia-Pacific is shifting against the United States, as China and North Korea challenge the credibility of U.S. security commitments and the Pentagon faces spending limits, according to a study released on Tuesday.”  

“Researchers at the Center for Strategic and International Studies, which conducted the study for the U.S. Department of Defense, were left ‘concerned’ that President Barack Obama’s ‘rebalance’ of U.S. interests toward Asia might not be sufficient to secure U.S. interests in the region.”  

“Congress required the Department of Defense to commission the report under the 2015 National Defense Authorization Act.”
