evidence: The next stage of this conflict is imminent. Azerbaijani President Ilham Aliyev may now have his sights set on seizing an extraterritorial corridor through Armenia’s southernmost Syunik province, which he has branded as the so-called Zangezur corridor. This extraterritorial corridor would link mainland Azerbaijan with the small Azerbaijani exclave of Nakhchivan, to Armenia’s west, which borders Turkey and Iran. [...] The Hamas-Israel war has been a tragic reminder that unresolved conflicts can derail the best-laid infrastructure plans. A stable and rules-based regional connectivity in the South Caucasus offers an important path for India-Europe connection. Armenia’s southern Syunik region, and the potential for broad-based regional connectivity that it holds, is especially important for Washington, Brussels, and New Delhi as geopolitical rivalries of the Eurasian continent continue to grow unabated. [...] Such conditions are present today in the nexus of interests knotted in Armenia’s south, and the outcome will have global implications for the shape of Eurasia for decades to come. But the opportunity for regional, rules-based integration in the South Caucasus is also real, and it, too, can be realized, if Armenia’s Syunik region is protected. Connectivity on Western terms in Eurasia is now contingent on Armenia’s territorial integrity.
