Thank you, Mr. Chair.
Thank you for being here to answer these questions on these vitally important topics.
I'm hoping that you can put this a bit into context because we're hearing things and the public is hearing things that sound very alarming. You have said that while it's not new, there's been an escalation and there have been more incidents. If you look at this in context, going back to, say, the Cold War, are there other periods when you've seen this kind of escalation and then you've seen maybe a pulling back, or is this unprecedented? Is this something that is completely new, that we've never seen before?
