The Russians' Difficulty in Crimea

Mike Downey: The Russians have literally dug in. They will fight hard for Crimea, which to them is sacred ground. He says they're starting to make the argument that if we just hold onto our gains on to any of our gains that we've made then it's a great success because it shows how tough our fighters are against the entire West. Downey: I don't see him reaching for a tactical nuclear weapon show. So I think his plan B is tough it out and look short of actually being driven out of Ukraine by the Ukrainian Forces.
