Of course its not the official stance and they'd never admit it. They're just hints left in plain sight to point at Russia. Putin's tactics used in Crimea are quite the same ones used by Stalin's Russia after WW2 in Eastern Europe. You can find all of them in decassified CIA reports. The only difference is the lack of insignia on troops, clearly designed to support the claim that the forces that siezed Crimea were rebels as opposed to Russian military. I disagree, Putin doesn't need to be slapped down, for this is too risky and could trigger a war. Nato (US) presence in Eastern (Romania) and Northern Europe (Poland, Eastonia, Letonia, Latvia), military and economic cooperation with these states is sufficient to deter his bulying ambitions. Hungary and Bulgaria have been ruled out for being too cosy with Russia.
