I'm going to jump in first here. I'm not a military expert, but, on the nuclear question, we're all focusing on Putin, and I think military and nuclear experts know that this is not a decision that one person takes and can execute regardless of what's going on around him.
I think what we need to be paying attention to is what is going on in Putin's inner circle. I completely agree with my colleague that we don't have full information, because Putin is hiding. However, we do have information about discontent among his defence minister and various others. We shouldn't be focusing on whether Putin's crazy enough to use nuclear weapons, because he by himself can't make that happen. I think that's an important point to keep in mind. There's a process that would have to happen, and other people would need to be on board with that.
The nuclear facilities...I think everybody read that Russian troops were digging in around Chernobyl; they were digging trenches and they started getting ill, then started retreating. My impression is they don't actually know what they're doing. They don't have a clear strategy. That makes it simultaneously scary and...because mistakes could happen.
We saw the fire in Zaporizhzhia, where the nuclear power station was on fire and Ukrainian firefighters weren't allowed in to put the fire out. I cannot imagine that something like that is on the agenda, because if a nuclear power station blows, that will affect Russia much more than Canada or the U.S. I can't imagine they're doing that deliberately.
