I agree with Jim. There are so many threats that are common to Canada, Russia, and the U.S. There's ISIL. There's North Korea. There are all sorts of threats like this, and we need Russia, being a Permanent Five member on the UN Security Council: the more we can do with them and understand with them.... Remember that in the Cold War the U.S. was big on having exchanges so that you'd get to see the other side's perspective. That's what things like the Arctic Council and others do.
That said, I think that in most cases when we're talking about security in the Arctic, we're talking about things like a mandatory polar code. We're talking about things like having the Northwest Passage actually charted for all vessels. In many ways, Russia and Canada have the very same perspective on our respective passages. We have a united front, in fact, against the United States, which sees the Northwest Passage and the northern sea route as potential international straits, whereas we classify them differently.
We also have the recent search and rescue agreement that requires the five coastal states to meet on a regular basis and share information about security and rescue assets and to start doing some joint activities, whether they're military-to-military, because they're the ones charged with doing search and rescue, or other agencies. But if we tone down the rhetoric and work with Russia on the areas of interest, we may actually find, then, that on areas like the Ukraine, we can start to chip away at what they're doing there, which we're condemning.
