you miss the point - it isn't Florida with the "stand your ground", it is international waters where one side's "reasonable" most probably means absolutely nothing to the other side(s). You shoot at something in your denial zone - it is an act of war, and you open yourself to reciprocation. China, for example tries to establish various zones in international waters for the reasons of its national security - the US ships and planes still sail and fly right through rightfully without giving a flying f-k.
