 Could there be an Iranian-Azerbaijanian war? Firstly, no matter how shocking the results of the January 27th Terrorist Act are, it should be taken into account that relations between Azerbaijan and Iran have not been easy before. These relationships are full of systemic problems. The problem of the religious influence of Azerbaijanis in Iran and the influence of Iran within the country has been repeatedly raised in Baku at various levels. For its part, Tehran expressed its dissatisfaction with the strengthening of cooperation between the neighbouring country and Israel. The strengthening of the strategic relationship between Azerbaijan and Turkey has also caused concern in Iran. Russian political scientist Sergei Markedanov said this while commenting on the possibility of war between Iran and Azerbaijan. Secondly, the Second Karabakh War, which eliminated the old status quo in the Caucasus, forced Tehran to pay more attention to this direction. Until 2020, Iran was dealing with the Caucasus region on the basis of the residual principle and focused on the Middle East. Tehran's attempts to establish relations with Yerevan are seen in Baku as an obstacle for Azerbaijan to reap all the benefits of the victory in the Second Karabakh War. However, no matter how different the views of the two neighbouring states are, they have one thing in common. Both Tehran and Baku definitely do not want to fight anyone for the sake of the interests of third countries. Meanwhile, Iran and Azerbaijan have both common economic interests and an understanding of how military political escalation will hit them, said Markedanov.
