I think no one can predict this right now. Imho, one thing could help though: if European Union stopped to act like USA's lapdog and started to carry more pro-european policy, it would certainly help to solve the current crisis. Quid prodest, as Romans used to say. It's obvious that neither EU, nor Russia or certanly nor Ukraine will gain profit from current Ukrainian crisis. USA gain visible profits in either outcome: stable and democratic Ukraine as a bridge for strong cooperation between EU and Russian Federation makes USA a spare link in this chain. In the current scenario USA get: 1) scared Europe who needs protection from "evil" Russia, 2) market for their shale gas, 3) reason to put their military bases in Ukraine, Baltics, Poland, Finland, Sweden etc., 4) strong arguments for internal consumption to spend more money on military. And these are only the most obvious profits.
