Thank you very much, Mr. Chair.
Thank you very much, Professor Braun and Professor Robertson, for your presentations.
In the context of the defence of the North American continent, I will go to the Arctic. Also, in a different context, Professor Braun, you mentioned about Russia not being a superpower, but in all this equation, we are eliminating China. The defence relations between China and Russia are excellent at this point, and we have seen in history a lot of axis alliances, which created a bigger problem for us in the last century.
Speaking about the Arctic, how do you see that the United States and Canada will embrace, let's say, a better cooperation in the Arctic? You can say I don't know anything about the policy of the United States regarding the Arctic, and obviously, as you mentioned, we are a little bit concerned about the buildup of Russia in that part of the world.
