The attack on the Marine barracks in Lebanon was successful because of dumb @ss rules of engagement. The marines had .50 cal machine guns but the belts were not in them. The .50’s could have stopped the truck cold. The Cole attack was the same kind of thing. The sailors couldn't open fire on boats because of the rules and a proper security perimeter was not maintained. The Cole was there for very poor reasons… It did not need to be there but politics dictated that it should resupply there. A lot of good sailors and marines died because of dumb @ss rules of engagement.
You have no idea about life at sea or what naval power is about. Maintaining an open navigation on the oceans is absolutely critical to maintaining free trade.
