evidence: Last month, Azerbaijan used force to seize control over Nagorno-Karabakh, a long-disputed ethnic Armenian enclave, displacing almost the entire Karabakh Armenian population. It might seem that their exodus has paved the way for a comprehensive peace deal between Azerbaijan and Armenia: after all, if the Armenian presence in the region is no longer a political factor, what is there to argue about? Yet Karabakh was not the only source of conflict between the two countries. Behind it loom other territorial disputes. [...] Aliyev’s absence did not stop Pashinyan from going to Spain and signing a declaration recognizing the territorial integrity of Azerbaijan. He signed a similar document in Aliyev’s presence in Prague last year, but this time the text listed the area of Azerbaijan as 86,600 square kilometers: in other words, it included not only Karabakh, but also other enclaves that existed during the Soviet era. [...] Concessions will not only be necessary regarding Nakhichevan. In Soviet times, there were eight Azerbaijani enclaves in Armenia, and only one Armenian enclave in Azerbaijan. A simple swap, therefore, would be impossible. Moreover, seizing control over the enclaves of Yukhari Askipara and Barkhudarli would allow Azerbaijan to cut off the Yerevan-Tbilisi highway if it so desired. There are still plenty of challenges ahead, therefore: not only in defining and securing the enclaves, but also in providing access to them.
