 Less than one year ago our alliance said that we were going to transition from assurance to deterrence. Deterrence means you have to have capability, the capability to compel or defeat a potential adversary. You have to demonstrate that capability and you have to demonstrate the will to use that capability. So the exercises are a part of that demonstration of capability. The potential adversary has to believe that you would actually do that for them to be deterred. To communicate to a potential adversary, do not make a mistake, do not make a miscalculation, we are prepared. The United States is here and we're going to continue to participate in exercises and we're excited about doing that for as far as I can see.
