head examined

"Defense Secretary Robert M. Gates bluntly told an audience of West Point cadets on Friday that it would be unwise for the United States to ever fight another war like Iraq or Afghanistan, and that the chances of carrying out a change of government in that fashion again were slim.   "In my opinion, any future defense secretary who advises the president to again send a big American land army into Asia or into the Middle East or Africa should ‘have his head examined,’ as General MacArthur so delicately put it,” Mr. Gates told an assembly of Army cadets here."
