Having been to Armenia (twice), Georgia (twice) and Azerbaijan (once), I was well aware of the conflict although not of the complete details.  The US has, and may still have a designated special diplomatic representative (an ambassador) that concentrates on issues relating to the conflict over Nagorno Karabakh.  The main result of the conflict, as I recall, has been the isolation of Armenia.  At one point Armenia was without a source of fuel and had to restart an old, damaged by earthquake nuclear plant (I was unfortunate to have been there at the time).  There were issues over the reliability and safety of the plant (that should be of enough to be of concern to just about everyone in the region) but Armenia had no choice.
