From the introduction to an IISS Strategic Comment:
Hopes have been dashed again that Armenia and Azerbaijan might make finally make a breakthrough in their long-standing conflict over the Nagorno-Karabakh region. The two countries' presidents left a meeting mediated by Russia's Dmitry Medvedev on 24 June in Kazan, without approving the basic principles for the conflict's resolution. With many recent ceasefire violations in Nagorno-Karabakh and a growing arms race between Armenia and Azerbaijan, this latest failure leaves open the threat of a new war in the region.
