I think it is fair to say that the cyber-threat is a very significant one. Similarly, disruptions to major lines of communications at sea are a major cause of concern. In the Strait of Hormuz, the Persian Gulf, and the Strait of Malacca, if those sea lines of communication were ever interrupted, the effect on our economy would be absolutely devastating. Therefore we need to be very clear: do we want to maintain the ability to defend those sea lines of communication, or do we want to do other roles that allow our allies to invest more heavily in that, and help them in other ways so they can focus on it? That's what I see as the largest possible threat to Canada.
