Let me just add one point.
I've been working to try to get justice for the last three years. The first thing that was always offered up, when I visited government officials or parliamentarians in the early stages of this campaign, was “We're going to bring this case up with the Russians”. What we've learned very quickly is that the old technology of bringing up cases with the Russians has no impact whatsoever. Words basically don't do anything. They're not interested in words; they're interested in consequences.
What is the range of options, in terms of creating consequences? There are not that many options. We don't have jurisdiction over the crimes they commit in those countries. But the one thing that we have jurisdiction over in the west, which costs us nothing, is the ability to let these people into our countries and to let them use our financial sector. This is something we have the ability to do. It's something that they cherish, that they covet, and it's something that for no cost to us we can cut off.
That's the one thing and the only thing that we can do. We've tried every other option.
