I highly doubt if Azerbaijan would be foolish enough to station Al Qaeda linked Syrian rebels and other takfiri mercenaries directly on Iran's borders. Even if Azerbaijan did such a thing, then they certainly wouldn't boast about it.
If however Azerbaijan did the unthinkiable, stationing Takfiris on Iran's border and then ordering them to attack Iran,then Iran's response would be immediately, firm and decisive.
With just a few missiles Iran could easily eradicate the Takfiri groups. It would be like Iran flicking away a bug.
Considering the massive casualties that Azerbaijan is sustaining right now, I really don't think that they want to get on Iran's bad side.
Iran could very easily turn the tide of the war with a few dozen missile strikes. Especially since it's right on Iran's border. Even the Armenians are now flying drones above the Azeri army freely. It would only require Iran to lift it's pinky to finish the job.
Turkey knew that Iran is very sensitive to have ISIS terrorits on its borders.... and yet they flew them into Iran´s Northern boarder......this says it all.
Azerbaijani forces have sustained massive casualties and losses of equipment and material in their latest failed offensive, including high ranking officers.
For the first time the Azerbaijani army is trying to conquer densely populated areas in Artsakh and they've failed miserably.
Only time will tell if they will eventually succeed, however winter is approaching and It's also become painfully obvious now that the Azeri army has lost it's initial air superiority.
In the beginning, we would see Azeri drone footage every single day pretty much. Now I haven't seen anything for a while and the last time was recycled footage. To make matters worse, the Armenians are now releasing their own drone footage on a regular basis.
The Azeri military has lost over 200 drones, helicopters, aircraft, loitering munitions since the start of the conflict.
Like I said before, Artsakh is not Afrin and the Armenians are not the Kurds in Syria. Armenia has air defenses, fighter jets with BVR capabilities and they're constantly being supplied by Russia and to a much lesser extent ran.
So last time I checked the Azeri casualty count was at 7000+. Now there are some analysts saying 10,000+. Remember the Azeri army numbers 50,000. With injuries, Aliyev has lost atleast 1/3rd to half of his army to death and injuries
All I can say is that Erdogan better send reinforcements soon. I mean you have to keep in mind that the Azeri military has been trying to advance on multiple fronts. From the north, north east, east and south on several fronts.
So far however they've only had success in the south and their losses seem to be mounting as this appears to be turning into a war of attrition. Aliyev's only hope seems to be Erdogan sending enough reinforcements to push through.
It's become obvious since the start of the war that without direct help from Turkey, that Aliyev would not have been able to gain anything.
