If I may respond on that one, first of all, every single decision for us to assume command is usually directed from government to us. It's not something that we undertake on our own. We get a political decision to go ahead, but it's after careful consideration of all the aspects, including who is participating and who is partaking.
For example, in a case where we have the United States that is not a party to this thing, would we consider that if it were something that met with Canada's objectives? Yes, we would. But in the case of other operations with other non-signatories, depending on who they are, it would be on a case-by-case basis.
