As General Jacoby may have told you when you went to NORTHCOM, the United States has plans in place to strengthen our own ballistic missile defence against the emerging threat from North Korea and potentially from other nations as well. So the United States has a plan in place that it's executing.
In terms of U.S.-Canada collaboration on this issue, Canada is going to make its own sovereign decision as to whether it wants to engage in a ballistic missile defence cooperation with the United States. I believe that when the decision is made by Canada to revisit its current position, if a decision is made to engage in this dialogue, there could be fruitful opportunities for collaboration, but this is purely a decision for Canada to make.
