About the recent developments in Ukraine as Mr. Yanukovich left the parliement the american directly or indirectly armed thugs seem to be winning unlike the case in Syria.
There seems to be a provocation issue here in my opinion to force Russia to protect Russian strategic interests like military bases and previous influence on Ukraine to use force. There can be more provacations to do that.
The reason might be simple. the utter defeat in Syria can be reversed. Such as if Russia attacks Ukraine even in a small scale conflict that does not take place in Ukranian soil, america may start the air campaign over Syria and say you do it so there is nothing to stop me from doing what I want in Syria. Then can offer lets swap Ukraine will be yours and Syria will be ours.
Just a possible outcome of a military action over Ukraine. In my opinion if Russia keeps calm and keep control the american curtain of lies will surely leave as usual. There seems to be considerable support for Mr. Yanukovich as well. There also seems to be enough evidence that this is an american backed coup.If provocations are handled with calm and these issues are raised and used effectively the situation can be reversed.
