What are they complaining about?

The Joint Chiefs of Staff wrote a letter to the editor of the Washington Post complaining about this cartoon. They said it was "beyond tasteless", but totally missed the point. I see a Secretary of Defense diagnosing a crippled military as "battle hardened" and offering as treatment to be "stretched thin", with a torture punch-line that is pretty funny. The JCS have it in their faces and can't get it, not even from a cartoon. The artist was in fact supporting the military and criticising Rummy for his policies.
Well, here we go again with the freedom of the press argument.
