There is no universal model to solve all conflicts. There is one model to solve the Nagorno Karabakh conflict - a Karabakh one. All others substitute for the reality in the region for past 18 years, political scientist Levon Melik-Shahnazaryan told a PanARMENIAN.Net reporter. In his words, attempts of the Azeri party to return to the Aland settlement model are unsound. "Even the Kosovo option, which does not exist yet, is not acceptable to the NKR. What is discussed in Vienna now is merely basic principles, which we started discussing at the talks 10 or even more years ago. Saying anything specific on the Kosovo model is premature and senseless now," he emphasized.
