I was kind enough to read the article. Please allow me to retort, point by point.
Before I do, however, please note that I shall focus on the asserted facts of the article, which, I suppose, will lead a reasonable person to rethink the author's conclusions, given that many of the premises are false.
It states that in "2005 the focus of Canada's military effort reverted to the counter-insurgency mission in Kandahar." Wrong. It focussed on the PRT, and when I was in Kabul in 2003, discussions were already underway for many of the ISAF nations to push out of Kabul and into the provinces. As I recall, a critique of ISAF at the time was that it was sitting in relative safety in Kabul, neglecting the provinces. To this day, securing Khandahar so that the PRT can do its job remains the focus. Building schools, digging wells and what have you don't make news: operations that make those multitude of successes possible do, such as Op MEDUSA.
There is one line that is total guesstimation on the author's part:
"Hundreds, perhaps thousands of innocent civilians have died in such strikes, prompting angry family members and friends to join the insurgency."
Have civilians died in bombings? Damn straight. Have all of those bombings been from "heavy handed US strikes?" No fucking way. When US or other forces kill civilians, it is error, either of judgement in the assessment of the target area or due to blind, rotten luck. Not so when the taliban detonate devices, sometimes in the midst of children. To call what the US forces do as "heavy handed" is a blantant anti-americanism that holds up what is perceived as a largely white nation to one standard, while failing to hold that same standard of conduct to a "non-white" group, eg: it is racist.
The article talks of the 39 dead Canadians (accurate to the time of the article's creation). That number is nearing 80. 80 soldiers killed in action in some 6 years. We were at war against Germany for 6 years and lost thousands dead, and many more wounded. Some 40,000 if I'm not mistaken. In the past year alone, there have been well in excess of 80 murders in Canada. Those deaths in Afghanistan, though tragic, are indeed noble because of the sacrifice those people knew that they could be making. Where is the nobility in getting a shiv in your back because you wear the wrong colours in the wrong neighbourhood? Because your husband is an abusive wretch? If I had a choice of the method in which I would meet my maker, I would rather it be in the service of what I believe to be right.
39 deaths (at the time of the article's writing) is not a sobering number. Neither is 80.
I shall only examine one more point. It is this:
First, it's argued that the mission is necessary to protect Canadians from the threat posed by the Taliban and Al-Qaeda. This is a serious argument, but it can be exaggerated. The Taliban do not pose a threat to the existence of Canada. They're not about to invade. Nor are they developing weapons of mass destruction and missiles capable of reaching North America.
First of all, the author is correct in that Canada will continue to exist. I just hope that ALL Canadians will continue to exist. Unlike the author, I care about the parts of Canada, not just its mere existence. This includes my family, my friends, strangers: Hell, it even includes Montreal Canadiens fans!
We know that they aren't going to invade: what kind of fool does the author take us for? No "missiles" capable of reaching North America? Dude, that author has to get with the times. This is not a nation-state, such as Germany, building V weapons and launching them en masse prior to the Panzer invasion. These are fanatics who stab stewardesses and drive planes full of people into buildings. These are people who strap bombs to the mentally challenged and then blow them up remotely. These are people who would go to any lengths to see you strung up because, oh, I don't know, because you reject God.
I cannot read any more of the article, because in only a few paragraphs, the author has proven himself to be ignorant of the facts, head firmly in the sand to the reality that (a) the USA is not all that bad and (b) extremism is a threat to us all, be it Islamofascism, or the blatherings of Lenin's little idiots, such as we see even in our House of Commons.
