I disagree Layla, on two counts:

1.The behaviour this time around is even faster and louder than with Syria 2014ish: I mean, Trump's announcement was just made and voila, literally the top half dozen stories, above the page, are flailing and screaming that Canada has to do something right now.

2. Even if we take your view, that the loudness and speed of reaction was the same for Syria 2014ish, I disagree with your claim it did not have an obsessed-with-America aspect to it. Absolutely it DID have that aspect, the thing turned into an Olympics competition of Canada self-proclaiming itself in competition with the USA, complete with frequent scorecards of how our numbers were doing compared to theirs. It was display exhibit "A" in obsession-with-the-USA.
