I'm thinking Obama's sanctions are smoke and mirrors. They are targeting individual Russians, Putin's buddies, but they aren't stopping the flow of dollars into Mother Russia:
US Buying Russian Helicopters for Afghanistan
Sanctioned Russian Has No-Bid Contract With US
I understand why we don't want to turn Europe's heat off, but there must be a way to get around that. Gas exports, anyone??
I don't believe Obama et. al. are taking this mess anywhere near seriously enough.
