Right but Canada isn't actively invading another country to conduct a landwar by rolling columns of armor and infantry into another countries' territory and it isn't actively hunting the civilians of the country it is invading, so if someone were to fly a bunch of military drones around Canadian airports, it would scare a whole lot of Canadians as you say and whoever did it would have a lot to answer for.

Now if those Ukrainian drones started clearly targeting civilian aircraft and civilian portions of airports and killing russian civilians at a mass scale, that would be a different question, which is another way of saying Ukraine does not fight in a manner anywhere near as cowardly as russia does.
