Thanks for the link.  I am always impressed with the complexity just under the surface.  This appears to be a great move for Putin in this giant chess game.  I have, for a long time, assumed that Putin will do everything possible to avoid pipelines from the ME to Europe.  It looked like a brilliant move when he went to war with ISIS after the door opened following the terrorism in Europe - forcing the US to go from arming/training ISIS to also fighting them.
