I would say that the issue of sovereignty obviously is absolutely critical to us when we're talking about North American defence. We keep a very close eye on any effort by NORAD that looks at modernizing or changing the way they do business to make sure that Canada's sovereignty concerns are kept first and foremost in those discussions. Being interoperable with the United States to pursue military operations is not surrendering Canadian sovereignty. In fact, it's exactly the opposite. Being interoperable with the United States lets us remain an equal partner because we have capabilities to work shoulder to shoulder with our most important ally.
The other benefit of remaining interoperable with the United States is that the United States sets the bar for any military operation of significance around the world. By ensuring that we are very interoperable with the United States, Canada can operate in pretty much any foreign military operation and not only operate but also assume a leadership role, which we have done several times.
