Besides, they didn't mention John Kerry. The message was clearly addressed to one "Jon Carry." Good luck prosecuting what someone "meant" rather than what someone actually did.
You see, the military brass are so blooming ignorant that they will never find Carry. They didn't study (like Kerry with four D's at Yale in his first year, almost flunked out). They didn't marry a billionairess who was always three sheets to the wind, except when she was straight-arming her second hubby. Etc. Etc. They will never discover the butt of the joke because they got stuck in the military.
