The first thing I'd recommend is that you read the new paper “Future War NATO?”, which just came out this week. It is on the GLOBSEC website. We go into great depth about this.
I think it's important for Canada to understand that hybrid warfare, cyberwarfare, and what's been called “hyper-warfare” are not separate. They're part of a new escalation ladder that challenges fundamental conventions on traditional deterrence. It's all about relative military power. There are 120,000 Russian troops, many high-quality, on the far side of the Latvian border. The main problem is that if our conventional relative power weakens further, then the nuclear threshold could well drop. That is a very real danger. My own country is very profoundly concerned about that.
