Nikol Pashinyan promised to declassify information on this topic.

“According to my personal conviction, we lost the war because the fifth column operated in our army. I think that these facts will become public in the near future,” TASS quoted the head of the Yerevan Cabinet of Ministers.

BLiTZ wrote: the pro-Turkish vector of official Yerevan’s foreign policy was not to the taste of the Armenian population, which does not believe in the sincerity of Ankara.
