Newsweek reports that Gen. Shelton was in fact pretty open and frank in his criticisms of Wesley Clark:

To say Clark was unpopular among his fellow officers in the military is an understatement. As he rapidly rose through the ranks, he was widely regarded as a champion brown-noser and know-it-all, a sort of Eddie Haskell in Army green.
In conversation with friends, Colin Powell would privately put down General Clark as "Lieutenant Colonel Clark" i.e., a perpetual eager-beaver wanna-be. Some officers questioned his judgment. Talking to a high-ranking Clinton administration official, Gen. Hugh Shelton, the former chairman of the Joint Chiefs of Staff who engineered Clark's firing, bluntly referred to Clark as a "nut."

And FOXnews uses the "nut" as a "FOXnews political anal lisp".
