The answer to that will be awfully speculative. I can only give you an opinion.
By virtue of having operated submarines for as long as we have, and by virtue of the capability of the submarines that we now possess, we have in effect become part of an international group of professional submariners. As part of this group, we share information about movements, capabilities, and techniques that we would not otherwise have been able to acquire or maintain.
Do you want to add anything to that?
