Paul Craig Roberts explains the situation in the Ukraine in this interview. It is not the western government line that the main stream media force feeds the dimwitted public. Nothing is how it appears. The truth is lost when US dominance is at stake. Putin understands what incompetents both Obama and Kerry are and simply ignores them. Could get real ugly. Start at the 5 minute mark.

Also, he has published an excellent article exposing the bull shit that Russia is the problem. The US is the problem and they are losing control.
