Yeah, since everything I said is true, I should be sarcastic and call it sarcasm.
No, its because you doubted the need for a country to even have a military, and that was actually sarcastic, but your reasoning wasn't displayed until your second post. Unless, of course, you actually think Canada and the US should actually, in fact, disband their militaries for the reasons you stated. Then, you would not be being sarcastic. Which is actually a definite possibility, since in your third post you basically said you're not being sarcastic. So really, there isn't any way yet to truly know what you mean, if you know what I mean. And I say that without any sarcasm.
