and to appeal at home, and to a global audience, the information the united states and others provide about russian troop build ups. the russian posture in their diplomacy, public statements and propaganda gives vladimir putin the maximum space to operate and to potentially move into ukraine and to blame the united states or the west in some fashion for not taking his diplomacy seriously. until we see the russians pivot to a substantiative negotiation, that continues to be the scenario that we have to be prepared for. and to richard engel, we ve now confirmed reports over the weekend that russia has started to bring blood supplies, plasma, to the front lines for potential conflict. is that another signal? is that part of the sigh war or some demonstrable proof that they are getting closer to a decision and possibly a decision to use force?
