And now what, Mr. Obama?
As Russian-backed armed forces effectively seized control of Ukraine’s Crimean peninsula on Saturday, President Vladimir V. Putin of Russia requested —and received — authorization from the Russian Senate to use military force in Ukraine.
Within hours after receiving Mr. Putin’s request, Russia’s upper house of parliament, the Federation Council, voted to approve it, after a debate that warned of the apocalyptic consequences of failing to stop a fascist threat from spreading to Russia’s borders. The lawmakers direct considerable fury at President Obama and others in the West they accused of fomenting the upheaval in Ukraine.
The vote was unanimous among the 90 members present for the debate, and it was clear that forces allied with Moscow were largely in control of the disputed peninsula.--NY Times
Russia sees the turmoil in Ukraine as a threat and perhaps a way of acting in opposition to the US. For it's part, the US is unable and unwilling to intervene. Regardless of how Washington and the media tries to explain non-involvement by the US, Russia and the rest of the world will see it as a sign of waning influence by the US on world events.
