The Georgian crisis in summer 2008 has allowed to highlight differences in interests and mostly in conceptions and perceptions concerning security between Russia and Western countries. Thus, if Moscow’s proposal aiming at establishing new security relations between countries in the Euro-Atlantic, where it would be fully integrated, has been met by some countries with politeness and interest, the fact still remains that the Russian method for demonstrating in practice the weaknesses of the current Euro-Atlantic system can only have resulted in distrust from Western partners. The ambiguity of Russia’s attitude shows in its wish to integrate in such structures, its desire to cooperate and its speech affecting not to fear the isolation it has been seeking to break ever since the collapse of the USSR.
