As far as i can make out on the ukraine - it's pretty much straight out of the playbook of western destabilisation tactics (there is literally a playbook - wikileaks (i think) leaked a US army manual on destabilisation that includes methods for fomenting protests, terrorism, sniping of protestors and blaming it on governments etc.).
This started when the EU were pushing austerity and subservience to western oil companies (chevron especially), banks and opening the door to NATO; when russia offered a price reduction in gas and a massive loan on much better terms than the imf were offering. The EU refused to deal unless russia wasn't involved - understandably Yanukovich wasn't inclined to be 'austeritied' like south america and europe and pulled out of the deal. This is when the push to foment the protests started.
Proper facists notwithstanding (and there are plenty of them) there are undoubtedly genuine greivances and genuine protestors in ukraine (though mostly split on ethnic lines) - but it's known that 'our' side has heavily influenced the direction and strength of these to their own ends (USA has spent 5 billion on getting ukraine to be nato friendly over the last decade).
The actual coup that happened to me had the hallmarks of a usual modern western intervention - foment protests, then mysterious snipers shoot both sides - the government is blamed etc. The same tactic started the syria stuff off; it was also tried in venezual in 2002 (but failed - looks like their having another go there now)

None of that's to say Putin's the goody obviously; but honestly in world affairs he doesn't come close to what oceania gets up to (remove the 10 tonne plank of redwood from our own eye first).
We'e been encircling russia with nato since directly after the USSR fell (going against the promise bush made to gorbachov) - america's got something like 600 bases in other people's countries, russia's got 3 or 4?
