There has been a theory that the possibilities of Ukraine and potential shale gas were part of Putin's thinking in terms of moving into Ukraine. I'm not sure that's the case. I think it had more to do with Yanukovych's fall from power than anything else, and concern that it might reverberate into Russia.
Development of shale gas in Ukraine and Poland, there's tremendous potential there, and other countries in Europe. As you indicated, sir, I do think it has serious potential and could do some harm to the Russian economy. I don't want to cause harm to the Russian economy unless the Russian economy threatens the west. Right now under Putin, I would say that's the case.
