The experience of Post-Soviet security cooperation looks unimpressive compared to the successes of NATO and EU. However, the main goal of the first stage of cooperation of the former Soviet republics (1990s) was peaceful disintegration, not integration. In the second stage (2000s), the creation of collective crisis reaction mechanisms did not lead to any interventions despite the obvious need for them. The explanation is that sovereignty has a higher value than regional integration for the member-states. However, this does not mean inefficiency of regional organizations in Eurasia, it simply shows a difference from Western models.
