The SS Cole allowed a small boat of Arabs to approach it. As the US was anxious 'not to offend' their Arab host which 'graciously' allowed an American warship to dock in their port these terrorists were allowed to go as close as they did. In fact, the 'guards' on board the SS Cole were not even allowed to have or were given ammunition for their weapons so as to prevent any 'accidental insult' to their Arab 'hosts'. It was the SS Cole incident that convinced me an American invasion of Iraq was doomed. If you do not know how to conduct yourself around Arabs - which the US obviously has no idea of - stay out and send assassins, not an army. Do it the Arab way as the Western way is folly among them.
