You see the big powers have some unwritten rules. Each has full control over their own backyard. That's why the soviet union blinked first during the Cuban missile crisis. The US will blink first here. Russia could actually annex all of Ukraine and the US will do nothing - other than talk.

The cost of US intervention is simply too great for no gain at all, other than protecting an ego, and the US is quite happy with a bruised ego on Ukraine

Nearly a hundred pro-Russian protesters in the eastern Ukrainian city of Donetsk have seized two floors of the regional government building, after the self-imposed Kiev government appointed a local oligarch as a Donetsk Region governor.

In the building there are currently over 20 journalists and deputies of the local parliament, according to ITAR-TASS.

Earlier on Monday morning thousands of anti-Maidan activists came to the building of local administration. They were chanting "Taruta - out!" and carrying Russian flags and banners reading “Russians are our brothers.”

Hio iko. The famous pussy riot

Its down coz of the un-certainity, foreign investors are scared but that aint enough to shake Putin. Russians dont import oil or natural gas. They rarely need the USD. They own Europe.

Its not that simple. If you dont buy oil from Russia then supply will go down and the prices will skyrocket. No one wants such a situation. Oil prices are enough to cause a revolution in any state in the west. Thats why those who play games with it have to go down - read Sadam and Gadaffi.
The banks in Europe are surviving on Russian money, if they pull the plug wait to see countries in the EU go down. Its not that simple as you assume, that's why the wise lady of Germany is calling for caution.
