Armenia is not Muslim. Iran is Muslim. Turkey speaks of reclaiming Azeri territory from Armenia. Does it also seek to reclaim Azeri territory from Iran?
They won't openly say that but Iran accuses Azerbaijan of supporting Azeri in Iran.
-----------
Iran's Azeri population is the largest of all minorities at approximately 22 million people, around 25% of the entire Iranian population. They are a Shi'a, Turkic-speaking nation who live primarily in several provinces in Northwest Iran. This minority suffers from linguistic, cultural, and ethnic discrimination, and its region’s natural resources are essentially looted by the central government. There is rampant unemployment and poverty in the Azeri regions, and there has been an effort by the government to “Persianize” the Azeri provinces. Admittedly, a large number of Azeris have overcome discrimination to become elite members of Iranian society. Grand Ayatollah Khamanei says he is an ethnic Azeri, though few believe this claim.
The government in Tehran arbitrarily arrests and tortures Azeri political prisoners calling for Azeri independence and clamps down hard on Azeri student demonstrations at the University of Tabriz. The South Azerbaijan National Liberation Front (GAMAC) states that Azeris don’t have access to the Iranian political system or educational system in their mother tongue. In late 2013,
5 Azeri political prisoners went on a hunger strike after Rouhani failed to implement his campaign promises. Iran has undertaken efforts, quite successfully, to create friction between Azeris and Kurds, as each are battling to create new provinces in Iran and bills of rights that protect their own minority interests. Having said that, in the spring of 2009 explosions at a police barracks in Western Azerbaijan province were said to be carried out by Azeri and Kurdish separatists purportedly working together.
Groups like GAMAC and the Azerbaijan Liberation Front (ANRO) seem more committed to a non-violent struggle at the present time, though an armed rebellion could occur given ample external support and a rise in the current trend towards nationalist separatism –
a trend that Iran now sees as a threat to its national security. Even if armed struggle is not the current course for Iranian Azeri groups, Azeris have their own country to the north of Iran that is already aiding Israel in pursuing an agenda of Iranian destabilization. Such an effort on the part of Azerbaijan is based not just on the unresolved Iranian Azeri issue - which it has historically tried to stay away from - but also because of other bilateral points of contention with Iran.
