May I add to my response? I should also say that we are members of the Arctic security working group, and John sits as a member on that committee. It's interdepartmental as well as territorial, and with other partners, and it's a good forum for exchange of information that helps this interoperability, amongst other things. We also participate as observers in operations like Nanook and so on.
On April 27th, 2009. See this statement in context.
