Russia creates its own version of NATO in Central Asia to be prepared for big war
The Collective Security Treaty Organization (CSTO) follows the instructions from President Dmitry Medvedev, who ordered to increase the military constituent and develop the coalition force development. A strong military group, which may appear in Central Asia in the nearest future, will make the CSTO become an analogue of NATO. The following post-Soviet countries are included in the treaty: Armenia, Belarus, Kazakhstan, Kyrgyzstan, Russia, Tajikistan and Uzbekistan... [it goes on to say that] the struggle for the energy sources on the Caspian Sea and in Central Asia may lead to armed conflicts in the region.

Couldn't they come up with a better name than CSTO? "Sisto"? "Kisto"? Well, it doesn't sound as threatening as the Warsaw Pact once was, but you can bet that the Russians will keep expanding it as long as they can find "willing" new members.
