I disagree. If they placed a destroyer 100 yards off the shores of New Jersey, and an American group blew a hole in the side of their destroyer, whose side would you be on? A destroyer is a Navy war boat, and during times of unrest in the middle east, if you port in a dangerous harbor, you have to expect these things to happen. I don't condone the action, but I also don't condemn it either. I also do not consider it a cowardly act. Who was cowardly? Were the Kamakazi pilots cowards?
They consider this war, and are fighting with everything they have. Many people are at war with the US, whether or not the US wants to recongnize this fact or not.
