Such a severe aggravation of the situation in Nagorno-Karabakh has not been observed since 1994 the time when the conflicting parties reached an agreement on a ceasefire. By September 27, 2020, the situation in the military-political plane has reached its peak. On the morning of September 27, in response to another shelling of Azerbaijani positions by the Armenian armed forces, the Azerbaijani side took large-scale actions along the entire front line in the Nagorno-Karabakh conflict zone, thereby resuming full-scale military operations, pursuing the goal of militarily liberating the remaining Azerbaijani territories which were under occupation over 26 years. The negotiation process was completely disrupted. This working paper analyzes the rationale and the reginal as well as international implications of the current events.
