I'll just add to that. You realize that what Putin is doing is in a region of undefined geography of his vision of a Eurasian continent, the third pole as he wants it to be. Whilst in the Arctic other than the delimitation of the continental shelf and planting a little flag at the bottom of the sea and all of that, in fact there is no contest. In fact the only litigation remains between Canada and the U.S. Between Norway and Russia it has already been defined and we have our own delimitation process to go through.
So there is no area to be claimed for the Russians and the Russians control an overwhelming majority of the whole area. It is not as it was, an expansionary place where you would want to make mischief. And I really agree entirely and I think we say exactly the same thing, that in the Arctic it's not an area where you want to have a problem with your neighbours.
