Nile Gardiner from Heritage writes on the Telegraph’s website:
This is bad news for all who care about the US commitment to the transatlantic alliance and the defence of Europe as well as the United States. It represents the appalling appeasement of Russian aggression and a willingness to sacrifice American allies on the altar of political expediency. A deal with the Russians to cancel missile defence installations sends a clear message that even Washington can be intimidated by the Russian bear.
What signal does this send to Ukraine, Georgia and a host of other former Soviet satellites who look to America and NATO for protection from their powerful neighbour? The impending cancellation of Third Site is a shameful abandonment of America’s friends in eastern and central Europe, and a slap in the face for those who actually believed a key agreement with Washington was worth the paper it was written on.
