I appreciate that.
You've been very clear about the importance of securing critical infrastructure. My colleague opposite has already asked about it.
In the case of the threat of Daesh, for instance, the pendulum swings, and has swung over the years. Particularly after 9/11 there was an emphasis on radical Islam, if I can put it that way, and countering that particular threat. However, can you go over what you said about how important it is to secure our critical infrastructure?
If we're listing threats and ranking them in terms of danger to our national security, do you think critical infrastructure is a more important area to focus on right now than what we've been looking at in the past, after 9/11?
