There are different dimensions to the question you just asked. Thanks for asking it.
My view on this is that we must be very careful. We should not fuel the fire. One of my strong pieces of advice is to please try to compartmentalize. Do not mix what's happened now in Ukraine and Russia with what happened in the Arctic.
To the extent possible, we need to address the two issues separately.
We shouldn't use the situation in Ukraine as an excuse to take a harder line in the Arctic. I would say that probably the best way to proceed is to deal with the two issues separately.
Does Russia pose a medium-term or long-term threat in the Arctic? Possibly, and we need to take that possibility into consideration. But it's critical to ensure that neither Canada nor the U.S. is to blame for triggering a potential arms race or escalating tensions in the Arctic.
In recent years, Canada has often been depicted, by the Europeans in particular, as the most aggressive state in the Arctic, the one with the strongest and firmest stance. And that attitude could trigger other behaviours, especially on Russia's part. It could use Canada's aggressive position to justify its own.
Canada's and Russia's respective identities are deeply intertwined with the Arctic. And that is not nearly as true for the other Arctic states. To be Canadian is to love the Arctic, and Canadians have a deep attachment to the Arctic. News of tensions or problems in the region always meets with strong reactions from Canadians coast to coast to coast, whether they live in Vancouver or Newfoundland, regardless of their language or preferences. The vast majority of Canadians care about what is happening in the Arctic, and that must be taken into consideration. That's also the case in Russia.
