Nagorno Karabakh army is the most efficient army in the region while Azerbaijani Armed Forces are still in a sad state, Director of "Central Asia and Caucasus" Sweden based Center of Strategic Research Murad Esenov told RBC newspaper. In his opinion, Azerbaijan will not dare to launch a war against Nagorno Karabakh and Armenia at present. "During the recent 10 years there were no fundamental changes in the Azeri army and its military efficiency remained at the same level. The Karabakh army, on the contrary, is noted for its skillfulness and combatant value", the expert said. According to the source, member of the Academic Council of the Institute of National Strategy and deputy to the editor-in-chief of Spetsnaz Rossii newspaper Armen Asrian holds the opinion that Aliyev is likely not to content himself with strict statements. "If there is no pressure from outside, Aliyev can start a war. In my opinion, which is probably a bit preconceived, Azerbaijan will certainly lose this war, though Azeris may believe in their victory", A. Asrian said.
