Armenia, Azerbaijan: Russia, the West and Nagorno-Karabakh

Azerbaijan accused Armenia of stoking unrest in the disputed enclave of Nagorno-Karabakh after a gunbattle that killed 15 people March 5. Azerbaijan is using its petroleum wealth to arm itself for a potential conflict with Armenia over the separatist region, which on paper belongs to Azerbaijan but in reality is controlled by Armenia. The West does not want to see this conflict re-emerge, but Russia does — to a point.
