With the capture of Crimea, Ukraine, Russia has effective control of the entire black sea. There is no European country that has access to the entire coastline of this tremendous military resource. Obama by his ineffective, seemingly conciliatory statesmanship gave Putin a walk-on to control of Ukraine Naval Bases in the Crimea region. The Crimean’s, mostly Russians, welcomed Putin like Austria welcomed Hitler.
The only Black Sea country not supportive of Putin is Romania but with the combination of America Hating Kerry and Obama they are in danger from Putin.
