As I mentioned earlier, the key thing for Canada is the north warning system and NORAD's relationship with it, and then from there the acquisition of intercept capabilities to ensure our capacity to deter, relative to the Russian strategic doctrine of the threat to escalate in order to de-escalate. You have gaps or command-and-control seams between various command structures, or you have capability gaps. Those can be exploited politically in this case to advance the interests of Russia.
That's the key thing in my mind, and it's really the interface for Canadian vital interests in the alliance with NATO. Our current forward commitment, given our available resources, is probably as much as Canada can do. I can't see our doing any more.
The important thing for Canada, as it is for all the allies relative to the threat that the Baltic states perceive, particularly Poland and Romania as front-line states, is the need to symbolically commit—this is part of communications and deterrence—and communicate that the alliance will stand together. That, I think, we are doing fairly well.
