Thank you.
In my remaining time, I have a question for Dr. Charron. It was interesting that the three general objections you listed for Canada's participation in ballistic missile defence going back to 2005 echoed almost identically the three points made by Colin Robertson, a previous witness: whether it works, the cost, and the impact on geopolitical stability.
How would you say each of those things has changed since 2005? To me, it would seem that in terms of whether it works, the technology has improved. It's confidential or classified, but it's obviously having more impact. Cost has been shared, or potentially shared, as with the U.K. example. Then there's the impact on stability.
Could you talk about how things have changed from 2005 to today?
