No. I don't care about my government too much, their whole system is fucked up and I'm a dark and edgy anti-social bastard. Sarcasm or not, no I don't support Canadian troops.
The whole Iraq/Afghanistan thing is pretty over-rated in my opinion. You can't fix anything by introducing outside forces - these countries are fucked. They'll end up killing each other anyways, and then who knows, maybe whatever comes after is better.
Now the soldiers individually, I don't mind them. Some are stuck up bastards, but the few I talked to and knew weren't too bad. I don't generally agree with what they're doing - the methods and ideology, mostly, I'm not really an anti-war person. But hey, it's their own life to throw away and their choice is as good as anyone else's.
Do I like my taxes going to things I have no use for and see little reason in? No, hell no. But there are plenty of other issues that I have with modern laws, and this one is hardly the biggest one.
So, eh, I'm pretty neutral. I'd support bloody slaughter, sure. But inefficient waste of human lives in some fucked up little country far away, not really. Especially when it's only really done as a suck-up move towards USA.
Although in that sense, then, as long as it concerns diplomacy and economics, maybe it's not too bad. Meh.
