Look outsider. Perché il conflitto Nagorno-Karabakh è diventato un problema cronico e irrisolto dopo la prima guerra? Quali errori hanno commesso entrambe le parti e questi errori potrebbero essere stati evitati? Quali sono gli aspetti delle squadre armeno e azere che meritano critiche?

I would say because Armenia thought it can keep it forever and was not interested in a negotiation.

Also Azerbaijan was not interested in any solution where Armenia had any say in it and wanted to control as much as possible. In addition to the international recognition of this territory. 

The compromise would have been some Armenian autonomy. But both sides had their maximalist ideas.

Armenia should have seen the economical and military situation coming, is my opinion.
