Looking at your map, the Poles are nervous. Putin’s main guy Stalin thought he had a piece of that. I doubt Obama would disagree if push came to shove.
Here's an interesting piece of trivia (or maybe it's not trivia). From Wikipedia:
Vladimir Putin's paternal grandfather, Spiridon Ivanovich Putin (18791965), was employed at Vladimir Lenin's dacha at Gorki as a cook, and after Lenin's death in 1924, he continued to work for Lenin's wife, Nadezhda Krupskaya. He would later cook for Joseph Stalin when the Soviet leader visited one of his dachas in the Moscow region.
