May 14 occupies a symbolic place in Russia’s military imagination. It marks the anniversary of the creation of the Warsaw Pact in 1955 and, nearly half a century later, the founding of the Collective Security Treaty Organization (CSTO) in 2002. The irony is difficult to miss: As the Kremlin works relentlessly to portray NATO as divided and hollow, Russia’s own security alliance system is showing signs of decay and it has become a symbol of Russia’s declining influence.
