I come to a different results following a similar train of thought. All the rumors about Golden Ruble, Golden Juan, Golden whatever... are a result of the need of BRICS countries to clear transactions between each other. They don't trust each other enough to use their own currency (there is no guarantee one of them will not print more than what was agreed). I believe they will sooner or later start clearing in Bitcoin. Once this happens there will be an enormous fight against Bitcoin. It can be done virtually in the cyberspace, but it can easily spill into the real conflict with real victims... If Bitcoin survives that then it will win. 

But will it bring peace? I don't think so. Same guns don't shoot people, currencies don't start wars.
