Sir, part of the answer to that is that I think there is some information there that's classified.
It's very clear, as you're probably reading in the open media, that the North Koreans are developing a capability—they've long had submarines, and we certainly saw the attack on the South Koreans years ago that sunk one of their warships—and that they've been developing the capacity for a submarine-launched ballistic missile, which I would characterize as nascent to this stage. It's not proven, and is certainly limited to their home territorial waters. We certainly watch it with a great deal of concern, because, as we've seen with their other missiles, it's a capability that they're growing and are able to refine and develop further. However, at this point I would suggest that as Canadians, we shouldn't be concerned. That is probably the single most watched submarine in the entire world, and frankly, I would be surprised if in times of conflict it went too far beyond Korean territorial waters.
