Actually I am surprised that they haven't said, "'F' it, if you Americans -- RINOs and Leftists -- want a real war, then that's what you'll get."
The problem is if we keep escalating this with the responses that we allow the Ukrainians, it could happen. All the Russians have to decide is that this is no longer an allowable proxy war in their estimation. We are playing with nuclear fire. As a former nuclear missile technician, I'm not exactly happy about that.
