I was a little surprised to see that, though it's gratifying to see our country take an actually ballsy approach to foreign affairs. Definitly one of the things I like about the Tories these days... willing to stick up for principles instead of always following the path of least resistance... or the most money.
As you can no doubt tell from the preceding paragraph, as a fellow Canadian I'm going to have to disagree with Artysim:
1) I think the chances of them losing their minority are quite low, though barring drastic changes it's unlikely that they'll get a majority in the near term. The Tory's nasty style of politics has shot them in the foot and cost them a lot of goodwill, but I'm pretty sure most Canadians would eat their own shoes before they saw idiots like Ignattief, Layton, or (heaven forbid) Duceppe become PM. Honestly, I might even consider voting Liberal one of these days... with the caveat that they actually have to choose a leader who isn't a gibbering idiot first.
2) Okay, this will sound ALMOST like a partial agreement. Staying out was a good decision. However, I supported the original invasion on the arguments given, and the assumptions that 1) the CIA was providing accurate information and 2) the war planning was being done competently. In hindsight, those two assumptions proved false, but hindsights a bitch, ain't it? Canada still should have stayed out based solely on our existing Afghanistan commitment (and to be fair, we ramped that up so that the US could transfer troops to Iraq, which is something like participating ourselves...).
As for the morality argument, Saddam was a dick and that was one of the original reasons I was willing to support the invasion. However, given the stated motivation for the invasion and the fact hat the supporting arguments proved invalid, I can't help but think that the US should have done something else instead... either bolster the Afghanistan mission so that it wouldn't have become the huge problem that it is now, or hit Iran or North Korea instead. Iran probably would have been more amenable to a liberation and less internally fractured, and North Korea (with the insane leader who used the intervening time to get NUKES) is probably the more dangerous of the three "axis of evil" states.
3) Okay, yes. Absolutely. Canada's military capacity has been utterly stretched to the limit by this mission, especially since the American deployment to Iraq meant that the situation over there got worse even as we were taking on more of the burden. But if you think that would be enough to stop us from following through on this sort of talk, you're mistaken. At worst, it would handicap the scale of the support. However, if one of Israel's neighbours decided to engage in open warfare against them, I don't doubt that we'd be there in a heartbeat, with economic and political support if not military.
Also, I'm pretty certain that any of the previous Liberal governments would do the same, whether or not they'd consider it good politics to state it publicly as the Conservatives have.
4) You always piss off someone in politics. I doubt this is sealing any fates, especially since this has basically been a position of the Tories as far as I can recall. If this was a significant electoral handicap, I'd expect they'd have dropped the position a long time ago. As it stands, it would appear that it either ISN'T such a handicap, or the Tory's political support is robust enough to soldier on past it.
Besides, I doubt they're going to lose their government. Harper is a political chess player, and the other political leaders are decidedly not. He plays the tune, and they dance. I don't know if he qualifies as a "master" political strategist, but in that crowd he might as well be.
