Rapidly, I think that on the NATO level, one of the things that has made NATO an exceptionally effective alliance in its past is the focus on interoperability and inter-operation.
In terms of the cyber domain, although there's been a declaration of cyber as an operational domain, I think that has been very much lagging.
In terms of defence of NATO systems, which I think Mr. Shea knows an awful lot about, there are definitely capability gaps there where I think leadership at a national level has to happen.
However, NATO is more than a military alliance; it's also a political alliance. I think, on that level, Canada's taking leadership in recognizing the fact that NATO needs a political strategy around cyber as a destabilizing environment is also really important.
Cutting off points of engagement and closing down mechanisms is not the way to go. I think Canada needs to show leadership on the fact that we can talk even when we have differences, recognizing the fact that the absence of a predictable escalation ladder in this particular area is something that creates volatility and danger for us all.
I'll let Mr. Shea answer the other two.
