However, Armenian governments have repeatedly resisted internal pressure to unite the two, due to ongoing negotiations under the auspices of the OSCE Minsk Group. In his case study of Eurasia, Dov Lynch of the Institute for Security Studies of WEU believes that "Karabakh's independence allows the new Armenian state to avoid the international stigma of aggression, despite the fact that Armenian troops fought in the war between 1991–94 and continue to man the Line of Contact between Karabakh and Azerbaijan." Lynch also cites that the "strength of the Armenian armed forces, and Armenia's strategic alliance with Russia, are seen as key shields protecting the Karabakh state by the authorities in Stepanakert". Some sources consider Artsakh as functioning "de facto" as a part of Armenia.
