If an Albanian/Macedonian illegitimate government was declared in the northwestern cities of Greek territory and its military armed wing was attacking the supply lines and military points of the Greek army, we would also call this a terrorist organization. Because this is not something that can be stretched, the definition of terrorism should not change according to you or me.
In the Western mind code, terrorists only come from Muslim communities, which is why you did not hear the news about the 7 Azerbaijani soldiers killed by terrorists, just a few days ago.
There is an illegal regime in Karabakh and this regime has a military wing. Although many convoys carrying military shipments have been hit in the last year, military shipments to these terrorists have continued using the Iranian corridor. What you are seeing now is a military intervention in this structure. Azerbaijan is conducting an anti-terrorist operation within its territory.
