I guess my brief answer is that there is no necessary connection there. There's nothing we can do on the security front that will influence how the energy relationship goes.
Certainly there would be some people in Congress, for example, whose votes on a question like this would be formed in part based on their perception of Canada more generally. How our defence relationship with them evolves may play into that to some degree, but we should not be thinking about how best to manage our energy relationship with them in terms of changing our defence policy.
