NATO's eastward expansion has destroyed the European security architecture as it was defined in the Helsinki Final Act in 1975. The eastern expansion was a 180-degree reversal, a departure from the decision of the Paris Charter in 1990 taken together by all the European states to put the Cold War behind us for good. Russian proposals, like the one by former President Dmitri Medvedev that we should sit down together to work on a new security architecture, were arrogantly ignored by the West. We are now seeing the results.
