Thanks.
My question is about ballistic missile defence. It's part of the emerging doctrine at NATO. It relates to both strategic deterrence and the aspiration of many new members to have that hard security umbrella because they're neighbours of Russia or they're near Russia.
Canada so far, since the 1980s, has remained outside of these sorts of negotiations and these sorts of discussions. Is that sustainable for Canada? Do you think we should join the NATO-led BMD or not?
