The main risk is Russia going one step further. In other words, what the Ukraine is worried about, as well as the other former Soviet Union bloc countries, is the fact that Russia is going to take back more areas within those countries, to enable it to have a bigger operating battle space if NATO decides to attack.
There is very little chance that NATO will attack, obviously, the way things are at the moment, but NATO did agree—I can't remember how many years ago—that they would not increase the size of NATO using other countries in Europe, but in fact, they've gone to 29 countries that are now involved with NATO.
Obviously, as I stated in my presentation, Russia is getting very paranoiac. They're not only worried about Europe. They're also worried about the Turks. That's another issue, because the Turks have indicated that whilst they are a member of NATO they also want to try to become the leader of the Muslim world, and those two ideas aren't computing.
Also the Black Sea fleet.... If NATO decides to stop the fleet from coming through the Bosporus and Dardanelles, that fleet is no longer able to operate in a warm water. The only port they now have is Tartus, in Syria. That's the reason why they're engaged in Syria.
