>>211851900 (OP)Well, I (almost) have a masters in IR so I should know a thing or two.
I would GUESS, that Iran's population is around 70 million. About 30% of population are Azerbaijani, 50-60% are Persian and the rest are various minorities: armenians, balochi, arabs, jews, qashqai, turkmen and the others
Iran is separated from Mesopotamia by Zagros mountains in the West, it has lots of dang ol oyle in Khuzestan region which is to the West of the Zagros and that makes it strategically vulnerable (Saddam tried to take it).
What else.
They are an Islamic Republic and that is a pretty unique for of government: they have a president, a parliament, but also Rahbar who is the leader of the country and the "Council of reasonability" (Idk what's it called in English) who together hold more details facto power. Also a special religious council to elect a new ayatollah. Religious minorities are officially represented in parliament: some places are reserved for Armenian Christians, Jews, Sunnis and Zoroastrians.
Uhmmm what else.
Iran is the weak point in my knowledge but that's what I can tell without googling
