The latest word as reported by the Wall Street Journal is that regular rotation of brigade-size forces, with the most modern equipment, will bring a de facto continuous U.S. military presence to the areas in question, which include the Baltic republics, Poland, Romania, and Bulgaria. It is easy to see that the immediate motivation behind this measure, as Deputy Secretary of Defense Robert Work indicated to the Journal, is to calm nervousness among some of those states about what the Russian bear is up to. But there are other implications of any deployment of this nature; if there weren't, then there would be no reason to expect the deployment to have the desired calming effect. We are entitled to be told, to a greater extent than we have been told so far, just what the strategy is behind this deployment. What exactly is the threat that we are trying to meet, in more specific terms than just "Russian aggression"? What sort of scenario do we have in mind? What would be the U.S. response to such a scenario, and what role would the newly deployed U.S. troops be playing?
