For anyone interested it may be good to get some balance by reading some of the articles Here;

Not everyone in the western world does or should believe the mainstream western press.
I have Ukrainian and Russian friends here and they have as many opinions about the situation as everyone else, what is clear though is that the current 'government' in Ukraine is extreme right wing and not liked by the majority any more than the Conservatives are in the UK my impression is that they are fairly evenly split.
The US with EC help has been stirring the pot for some time,(has poured 5 billion dollars into someones pocket there according to a leaked phone call by Victoria Nuland), and is in my opinion playing with fire.
At the end of the day the US is only interested in controlling the oil and gas that could flow through the Ukraine from further east.
Every other bit of US ( often with British and others support) adventurism over the last twenty years or more has shown that they don't care about the people or the future of the countries they 'help' only about what they can get out of it if anything.
I think the adventuring is American not Russian, Russia has enough on it's plate improving it's own infrastructure and economy and the Ukraine does not have enough to offer that would encourage adventurism from Putin.
