Mr. Chair, thank you for the question.
I will focus my comments on a national security point of view. I would say that what we have seen is a fairly significant change in the last four or five years. It's not just from an intelligence point of view and with us sharing more, but that everybody else is realizing that the environment has changed. The threat coming at us has changed in its intensity, in its velocity and in the number of actors.
I am, on the one hand, comforted by the fact that people are taking this very seriously; on the other, I'm very nervous about the intensity of that threat.
