The US has been incapable of putting ourselves in the shoes of a has-been empire, so when Russia sees expansion as a threat, we can't fathom what their fuss is about. But if you look at it from Russia's perspective, as a post Soviet Empire that is in severe retreat and is beset on many fronts, one can begin to understand some of their PoV, especially given the Syria-Ukraine-Caucasus entanglement stoked by Obama. Obviously a cretin like Putin takes all this as personal affront on behalf of all Slavs and results in this disaster.
