The United States could fight an old-fashioned war against North Korea if necessary, even while newer forms of conflict against terrorists and extremists continue, the Army's top officer said Thursday.
Asked whether the United States would be prepared to fight if war broke out between South Korea and North Korea, Gen. George Casey replied, "The short answer is yes," then added that "it would probably take us a little bit longer to shift gears" away from the type of counterinsurgency fighting that now occupies the Army.
