If I were an "intelligence" gathering agency, I might possibly have a reason to NOT inform the combantants as to why I was sailing in international waters. Hmmm?
If anything the Liberty's mission was like the "I'll never get killed" recklessness of a fresh teenager driver in a fast car. Magical thinking that was deadly. Magical thinking that even an unannounced sneaky visit into a hot war zone is safe on account of the US flag markings. James Deanish -- except the commanders there should have known better.
