Indeed, sir, on a daily basis we cooperate with U.S. forces to make sure that we have a shared awareness of our common security threats. We have a shared awareness of activities off our coasts, and we have a shared awareness of how our forces are posturing, so that we understand what is happening, particularly around the border when things are happening close to where we're doing business.
So I would characterize it as a very close and friendly partnership that fully respects national responsibilities for safety and security, that fully respects national sovereignty, and that makes best use of our resources to come up with a common understanding of what we are facing.
