If the wild wet comes back up there, just what would Canada do if Russia wanted to mine/drill in a area you claim? Just how far would you push this aggressive stance?
If it's just an area we claim, then I'd say let's not even claim it. If however we can prove that according to the established law of the sea it's on our continental ridge and so we own it, as per established international laws, then I would certainly defend that territory. Remember, the last thing Russia wold want would be a war over it even if it is militarily more powerful than Canada, on the simple grounds that if as per established international laws it is recognized as legitimately Canadian territory, the Russians would know they're in the wrong and so it would tarnish their international reputation and the trust of their neighbours in their respect for the rule of law. So it's highly unlikely they'd even bother claiming territory they can't prove belongs to them as per international laws.
But just for entertainment's sake, let's suppose they did claim it anyway and were prepared to fight for it. With ten times Canada's population, the Russians would certainly have an edge. I'd personally fight Russian on a number of fronts:
1. Militarily, with whatever we have.
2. Diplomatically on the international stage by getting other countries on our side to either fight on our side or at least declare an embargo on Russia on the grounds that it's adopting a dangerous expansionist policy.
Whether we win or lose, Russia is bound to lose too owing to the enemies would would have built for itself among its neighbour countries which would suddenly be more loath to trust it.
By the way the same applies to Canada. Should Canada claim land it cannot prove to own legitimately, and should it fight for it, even if it did win, it doesn't change the fact that even the US would be hard-pressed to defend Canada when Canada would clearly be in the wrong.
Honestly Ironsides, would you want the US government to side with Canada in a war against Russia over territory Canada would be claiming illegitimately?
Honestly, I appreciate our alliance with the US, but I sure hope the US alliance with Canada is also one based on principle, and not blind loyalty. I'd hope that if Canada were violating international law in claiming land it doesn't own, let's say Russian just for the sake of argument, that the US would stand on the principle of the rule of law and not blind loyalty to Canada.
And honestly, I hope Canada's alliance with the US is based on the same principle of the rule of law. Allies, yes, but only in full accordance with the principles of international law.
