The US policy WRT the Ukraine has been to condemn Vlad's actions and to do its best to ensure he doesn't annex anymore than he already has. Had the US "left the issue alone" Vlad arguably would have taken the rest of the Ukraine. Certainly Ukraine's neighbors thought so. Euro action alone wouldn't have stopped him.
You go off on a tangent talking about generalizations of government incompetency. You might get a few head from nods from fellow US bashers but you've not said a damn thing.
You're being called out, man up or shut up. Explain EXACTLY how US policy is to blame with regard to Ukraine. If your comfortable condemning US policy, then you should be just as comfortable explaining how the US is to blame in the Ukraine.
I'm not so biased to say the US hasn't cocked up things in the past and surely will in the future. I however look at policy on a case by case basis, and avoid broadly condemning actions. Might work well in the cocktail circuit but doesn't do anything but call your bias into question.
Face it, no matter the situation, you are predisposed to point your finger at the US.
