I'm afraid I don't have an answer for you. You'd need to ask the JAG about the international law constraints and our own legal constraints.
As I pointed out in my opening statement, I'm concerned that we in Canada have not done enough heavy lifting to precisely answer these types of questions—what our response would be and what our co-operation would be, both with the United States and among other allied partners, in particular middle-power partners. If the United States is busy in other conflicts, we need to be able to respond with other partners.
