Let's get real. If Russia wanted Ukraine, they would just take it. Something more must be going on here. Perhaps the USA's subversive efforts to dissemble Ukraine's economics from Russia might be a factor? Perhaps stiffing Russia for $4.8 billion in past due gas bills could be a factor? Perhaps privatizing a pipeline to Europe carrying a substantial portion of Russian gas might be a factor? Talking about Ukraine buying reverse flow gas from a pipeline majority-filled from the Russian end might be a factor? Perhaps USA wanting to control the throttle on energy to the EU as a geo-political ploy might be a factor? Pethaps the USA wants all these Euro area Nations in the same Central Banking loop instead of like Iceland, and that might account of why billionaire oligarchs have been the annoited leaders (hint, if you have a billion dollars you are a banker, like it or not). Perhaps attempting to outlaw the Russian language spoken in South and East Ukraine and referring to these residents as cockroaches (colorados) that need to be exterminated could be a factor? Perhaps allowing Nazis in the Ukrainian gov't did not sit well in South and East Ukraine where German Nazis killed 20 million+ Russians during WWII was a factor? Could this war be between Ukrainians and Ukrainians and not Ukrainians and Russians, because if it is Ukrainians against Ukraininans then negotiations should be between Kiev and the Separatists and could that be a factor? Could the "Black Hole of MH17" indict Kiev and could that be a factor? Russia has not invaded, but perhaps many South And East Ukraine Grandma's grandchildren working in Russia where there are jobs have dropped in for a visit to help Grandma and brought weapons to be useful , because Grandma is being bombarded by artillery, and could that be a factor? This is just another manifestation of the power of the Big Energy lobby in USA politics.. Control the Nation's energy and banking and control the Nation. Could that be a factor?
