The recent NATO summit in Wales, held against the background of the armed conflict in Ukraine, has brought back the Cold War atmosphere to Europe. NATO's partnership with Russia remains formally suspended. In fact, NATO is treating Russia more as an adversary than a partner.

The alliance is setting up a "Rapid Reaction Force" to deal with emergencies on Europe's eastern flank. The alliance's military infrastructure is moving toward that exposed flank, and closer to Russia's borders. NATO forces will now spend more time exercising in the east, and their presence there will visibly grow. NATO-leaning Ukraine, which the alliance alleges is an object of "Russian aggression", has been promised financial and military support.

The Ukraine crisis is not just about Eastern Europe, it is also about the world order. The Kremlin is seeking Washington's recognition of what it regards as its core national security interest: keeping Ukraine as a buffer zone between Russia and the West, particularly NATO. Washington, on principle, denies Moscow this "imperial privilege", and insists on the freedom of all countries, including Ukraine, to choose alliances and affiliations.
