That's a great question. It allows me to talk a little more about hubs. In developing the concept of the hub, what we did at the front end was consider the dynamics of the world. When Canada asks a military force to go somewhere, whether it's for humanitarian assistance or for security operations, normally it means that you're going to go some distance, and that you're going to an area that is devastated in some way or other. So our planning assumption is not to expect to have much there. We do not want to put a strain on the local economy as we start to move into an operation.
Yes, we do need to plan, and that's in essence what the hub concept allows us to do. We have modelled strategic lines of communication against tactics. In a global context, by studying the geopolitical realities, we know that there are parts of the world where we might need to be prepared to respond, sometimes without any detailed direction from government. This allows a level of flexibility, so that if government decides that a military response is required, we're able to carry it through.
