From 2006 to 2008 Russian government adopted an aggressive foreign policy toward the West, particularly the United States. In this article, the author claims that one should search for the main factor in the ‘feeling danger in the European borders of Russia’ and more clearly in ‘serious endangering of European balance of power’ from the perspective of Russian authorities after 60 years. I have tried to study the issue from the viewpoint of constructivists and tried to set forth the issues of Russian foreign policy in this decade and refer to aggressive policy of Russia in the second duration of Putin presidential. Then I show the importance of European balance of power and American anti-ballistic missile system in Eastern Europe for Russia.
