"But it is hard to square Dempsey's description of a world with sharply lower barriers to military power with his defense of the administration's strategic guidance and budget."
GOP has been attempting to clobber Obama and Democrats on this one - decrease in Defense Spending as per the last Debt Ceiling Accord. Paul Ryan does not believe Dempsey. GOP simply believes that the first and only job of Government is to fight a war (to protect assets of rich). Fortunately, American Public is with Democrats in reducing military commitments and GOP is unlikely to get any traction on increasing defense spending.
