Yes, that's fair. I would just qualify those comments by adding that Canada's tone has changed over the past few years. The tone taken from 2006 to 2010 or 2011 has softened considerably. For instance, the whole “use it or lose it” rhetoric has disappeared.
The members of Canada's military have played a pivotal role in that regard. They made it clear that their main task, their primary mission, focused much more on helping the various departments carry out their Arctic activities than on driving out submarines or conducting potential military exercises in the region.
And so the tone has softened in recent years. But I worry that Canada's reputation of being aggressive will stick for some time still.
