You clearly didn't read the posts. Experts in this area are telling you it is a huge problem, yet you want to ignore it. I guess you always know more than the experts.
As for the Cole, they were unable to protect themselves in port. It is much tougher to do so in the middle of the ocean. Additionally, a "small boat that could not get past the breakwater" is BS. It only takes a small boat to do serious damage, and 100 miles is nothing. And don't start preaching to me about boats and oil rigs, because I guarantee I have far more experience than you on these issues. Are you also an expert on radar? Do you know what size boats need to be to show up on radar? DO you know how weather affects radar?
Your argument here is totally flawed. I suggest you go back and read the posts, because you clearly don't understand the issues at play and the potential for terrorism and the adverse effects on the JDZ.
