Last comment because, well, I've learned to limit how much I go back and forth on these types of things.
First, even the article you liked didn't offer to turn over Bin Laden. It offered a discussion, asked for proof, etc. This isn't how international relations with a super power that's just had it's financial sector gutted in a once-in-a-decade event go. There is this retreat to minutiae that often happens in political debates. Sometimes it helps, but it usually does.
1. USA was attacked (for the second time) by a religious extremist.
2. They invoked Article 5, the only time in the history of the alliance that countries involved had a pre-commitment to jointly aid in defence. This isn't to say that individual Nato countries can't join together in other military exercises, like, say the invasion of Iraq. But that isn't Nato. That's UK + USA, it doesn't include Canada.
3. Every major ally of the USA responded by deploying troops to Afganistan. Even France.
You can talk about the "industrial complex through the sockpuppet war media" and yes we have to be careful about how much we trust reporters because black propaganda is sadly a real thing, but the constant denial of ground realities and suspicion of Nato is clearly false on the merits. People are not lining up to immigrate to Russia or China or Afghanistan.
Everyday people know that you have to try pretty hard to piss off Canada and if Canada is part of Nato maybe it isn't because of a giant world sized conspiracy theory. Maybe, just maybe it's because (mostly) peaceful democracies naturally want collective defence.
