So when he writes a concise tome suggesting that we might want to consider a different construct to defend the sovereignty of eastern European countries, you should read it and listen to him and this podcast. The book, ‘Beyond NATO’, offers a new security architecture for the region, which might make for less tension between the West and Russia and provide for more lasting peace than exists today in region.
