It's not just Zangazur. As another historically Azeri land, Göyça (Sevan) lake was also passed to the Armenians by the Russian army in the same years. Therefore, this expression is an attitude that can lead to incomplete and misunderstanding. It overshadows what kind of bandit story the Armenian state has.
ps:
Shown here are land bandits under Russian rule. However, ethnic cleansing and the forced migration of Turkish tribes started in the 19th century. Part of the list can be viewed here:

If you look at the 17th and 18th century map of today's Armenian lands, it is very difficult to find anything other than the Azeri feudal lords and Turkish tribes. It is clear in historical sources that the pedigree most of the Turkish tribes also who was where and when. With the domination of the Caucasus by the Russians, the Azeri dynasties were cut off and ethnic cleansing activities started on the Turkish identity almost all over Azerbaijan terriroties. Separating Anatolia and the Caspian from each other has been Russia's strategic priority in the region.
We need to understand well that what is referred to as the Armenian state was built on the remains of terrorist organizations established under the auspices of France and Russia in order to disintegrate Turkish lands. For this reason, modern Armenia is actually a structure that is largely isolated in its region, ruled by the Diaspora and doomed to the beg of Russia.

Also, there is another story on the other side of Araz.
The longing would be ashamed of itself, if it listened to Araz's story...
