Thank you.
Originally, NORAD's mission focused on surveillance of long-range aircraft. Now we live in a world of hypersonic missiles and the response time is limited to a few minutes.
Do you think things will evolve to a point where efforts to detect and destroy hypersonic missiles will be futile because the necessary response time will be so minimal? Is that something to be concerned about in the future? Will we have to change our strategy completely in response to outside threats?
