You are incorrect. A nation without the ability to defend it self if necessary is waaay worse off and vulnerable than having one less broadcaster on the airwaves
You live in a fantasy world. In the real world Canada only has two neighbours, Russia and the USA. Even if we put 100% of our GDP into our military we would be unable to fend off an invasion by either of those countries.
It is absolutely farcical to talk about Canada defending itself militarily given our actual geopoltical context.
In the REAL world, as opposed to your bizarre alien fantasy world, Canada's security depends entirely on its political alliances with other nations. ENTIRELY. Plainly we have to have something to offer to persuade others to take an interest in our defense, but there is no reason to believe that we have to offer something of a *military* nature. Plainly we have many other things to offer, in terms of trade, resources, economic integration, that would result in our Southern neighbour coming to see defense of our nation as a strategic interest.
Actually if you REALLY think about it you will quickly realize that the Americans have a strategic interest in defending Canada no matter WHAT we offer. They LIKE having a few thousand km security buffer between their Northern border and their nearest geopolitical adversary, and they like that for their own reasons.(*)
So while your comment SOUNDS like it's intelligent on the surface, the moment you give it even a little thought it collapses into absurdity.
(*) If you think about it for another few seconds you will also understand why Canada has so much of an interest in promoting organizations like the UN, ICRC, ICJ, WTO, ICC, etc., in opposition to the US. While we get along great with the Americans, enhancing the clout and credibility of international talking clubs gives us a buffer against their intrusion into our affairs by forcing them to "play by the rules" in a way that we NEVER would be able to militarily. In the final analysis Canada's security depends almost entirely on global/international agreement, especially by the Americans and the Russians, that the resolution of diplomatic and political differences ought to be conducted through international institutions. We're safe so long as everyone plays "by the rules", and we cannot POSSIBLY be safe, no matter how much we spend on our military, if either our neighbours decide to stop playing by the rules.
