Didn't say the Russians are credible, just that the Obama Administration has not made even the most basic case for military intervention.
They are winging things and making it up as they go along. They cannot be trusted as we have seen in Libya and Egypt.
Better to wait until we have some one who knows what they are doing in office before we go on any more adventures, especially when they tend to result in Al Qaeda taking control of an entire country.
