The Republic of Azerbaijan is simply a erstwhile USSR republic and 1 of the 3 tiny Caucasus states bordering Armenia, Turkey, Iran, Russia and Georgia, and to the east it has a long coastline of the Caspian Sea, on which is besides the capital of Azerbaijan - Baku. Of this triangle of states, Azerbaijan is the only state in which Islam dominates, as well as the most aggressive one. This aggression stems from a desire to regain control of Nagorno-Karabakh, a region formally part of Azerbaijan but de facto controlled by the autonomous, world-unrecognised, pro-Armenian state of Arce.
