It's been 0 days since I've been aware there's something called "MEDINT".
One thing I do know, this wasn't an "intelligence failure" - it *could* be an instance of what is called "inconvenient warning".

(also, it's "defence intelligence" not "military intelligence") #cdnnatsec https://twitter.com/Murray_Brewster/status/1248578073525698565

What is an "inconvenient warning" rather than an "intelligence failure" you ask, well let's as the CIA!

And here is a good thread basically explaining why governments have difficulty responding to threats and risks, even if they have intelligence about them. https://twitter.com/paul_scharre/status/1248593769370394630?s=20

So before we go nuts screaming "intelligence failure!!!" or "THE GOVERNMENT KNEW", I think we're going to have to wait a while to figure out who had this information, what they did with it and how they balanced it out with other information they were receiving.

Like, I'm guessing the fact that several dozen Canadians were killed in Iran that month *MAY* have had something to do with the distraction, and *MAY* have been the intelligence priority at that time. But I don't know we'll have to see.
But: Not an "intelligence failure".
