Yes, I am quite aware of why the Secret Squirrels were shutdown and CSIS stood up. Of course, it was more or less smoke and mirrors in that they took away the former Mounties guns and badges and gave them trench coats instead. The same guys were doing the same job under a different name albeit with more supervision, that's all.
You chain up your sheepdog too much, he'll not be as effective at guarding the sheep when a wolf pack comes calling one day.
Sure, at the present there are no major states in Europe who are eyeing the others with the thought of shanking them in the shower. So, the chance, just now, of a repeat of that scale of major armed conflict is low. However, there are other pressures building up right now with the insane intake of all these migrants. Some of these migrants are wearing out their welcome pretty swiftly on the backs of the Europeans who were there first. Some of these migrants are not "honest" migrants but outliers of the barbarians and are making their presence felt. It's not all Sunny Ways in Europe right now, else politicians like Mme. Le Pen would be getting SFA for votes. These attacks are a relatively new phase of the migrant wave and perhaps your scale might be blown out of the water over the next few years. I honestly hope not.
It's easy to say we're less likely to die now than we were 70 years ago. No kidding. Seeing as a Second World War scale conflict isn't on the go at the moment, that is a pretty safe bet. Of course that doesn't matter a fig to the little girls from Monday night, now does it?
