|RAF Typhoon with Russian Su-27 - June 2014|
I'm not sure there's a direct causal relationship or that Putin is petty enough to care about what an insecure Canadian political leader (and possible secret admirer) has to say about him, but it is probably true that things are starting to feel like the old days at NORAD. Not that we would know, because as Stewart mentions in Canada these things are secret. I disagree with his reasoning that this to keep the Russians in the dark about what we know. NORAD sees pretty much everything in the air around North America (because that's its job) and the Russians know it, and the Russian aircrew certainly notice when US or Canadian fighters pop up to say hi or radar waves bounce off their airframes.
The secrecy claim is also a little weird when put in the context of Europe where the RAF is happy to highlight their Baltic interceptions of Russian aircraft of all types, including armed fighter aircraft.
Then again, if the Russians are flying armed fighters near Canadian air space, it might look a little more concerning than docile and easy to shoot-down large bombers or reconnaissance planes. Not that anything would happen, but I imagine the dynamic changes and pilots' palms sweat a little when fighters meet fighters.
Perhaps also it puts a particularly problematic repurposed bomber procurement/corporate welfare project in even darker shadow by daylighting reality and thus the need for Spitfires (or maybe, just maybe checking out of the absurd Great Game altogether)...
