Thank you very much, Mr. Chair.
Thank you, gentlemen, for being here. It has been said that this has been a long study, and you've been with us several times. Thank you very much, not only for your service to our country but also for your service to this committee.
One of the questions that has been asked a few times is about the growing possibility of increased navigation through the Northwest Passage in the coming years because of climate change and melting ice. We heard the other day that this brings with it a high level of risk, rather than making things easier, which one would maybe assume.
What are the top security concerns associated with an increase in shipping? Maybe you can touch on the future cruise ships wanting to go through the passage as well.
