evidence: After its rapid military advance last week, Azerbaijan is set to establish full sovereignty over Nagorno-Karabakh, the country’s contested mountainous enclave that has been under ethnic Armenian control for three decades. With that dispute nearing a conclusion, Azerbaijan may now move to resolve its next point of contention with Armenia: the completion of the so-called Nakhchivan (or Zangezur) corridor. But unlike Nagorno-Karabakh, a carved-out corridor in Armenia’s south would have serious implications for the region, rewriting the geopolitical map for Iran, Russia, Turkey and potentially even Israel. In 2020, a Moscow-brokered ceasefire agreement ending the 44-day war between Armenia and Azerbaijan in Nagorno-Karabakh guaranteed "the safety of transport links between the western regions of the Republic of Azerbaijan and the Nakhchivan Autonomous Republic." Control over the land link would be managed by Armenian security forces as well as "the bodies of the Border Guard Service of the FSB of Russia."
