Chair, I'll answer the question in perhaps two different ways.
First of all, the spectrum of platforms and capacities that we have is sufficient to satisfy the threat and vulnerabilities that Canada has today.
What is the central element of our study related to continental defence and NORAD modernization is about the need for modernization and the need for people to be able to be ready for those threats and vulnerabilities of the future.
There are two aspects of it. We're very much focused on positioning Canada for the defence of our national interests and the security of North America in the future. That's the basis for analysis in the NORAD modernization review.
