fine, but the way that all states work at all times is by continuously attempting to shape and guide events to their own favor. they don’t stop just because the current event they are trying to shape happen to be of their own doing in the first place.The US had a major role in all of this. They rigged the elections in favor of Yeltsin who named Putin his successor, rebuffed Russia's attempts at joining NATO twice, and ignored Russias concern regarding NATO expansion. Then there is every color revolution they have helped push over the years, in order to boost this NATO expansion.
The current crisis is entirely of the US creation, as is the current Middle East crisis and whatever they end up causing in Asia-Pacific.
assigning blame is a tactic, not a strategy.
