The opportunities will change. You will need the capabilities to operate in the Arctic. I think the competition for resources in the fullness of time is something that we'll need to continually be aware of as a nation.
Given that we have the fifth-largest economic exclusive zone and the second-largest continental shelf in the world, those are areas of sensitivity. In terms of the sovereignty aspects, as you know, there are only a couple of claims against the sovereignty in the Arctic.
From those perspectives, both with key allies.... I have every expectation that they'll be dealt with through international law in the fullness of time, and then, as you say, we'll monitor intent going forward.
