Well, that's one of the things that need to be exercised and looked at. At the tactical level they'll do it, but at a strategic level we've stopped doing it, largely because we don't have the SACLANT position anymore. It speaks to the different areas of responsibility, the fact that USNORTHCOM goes out to 500 miles, that NORAD and Canada have a different area that they will surveil, and what the U.K. does versus NATO. It's often event-driven, so maybe we need to look at this more strategically and have a look at those gaps, because they are ones that can be taken advantage of.
