Only if your game documents the visit by American General Huyser [1] in the winter of '79 to Tehran and his direct communication to the Iranian generals of Washington's position regarding the future of Pahlavi regime.
You will understand nothing about world events since mid-70s until you wrap your head around US's decision to throw the Shah under the bus and prop up the Ayatollah regime. (Little hint for you here: have you noted IRI's enemies, Sadaam, Taliban, etc. falling off like flies at the hand of America while the robbed ones maintain their retarding [2] regime in Iran?)

[2]: Simply can not even imagine where Iran would be today if it had not suffered from more than 3 decades of sanctions, an entire generation maimed and killed in Iran-Iraq war, the continuing brain drain, and crippling sanctions based on the sock puppet regimes duly voiced "death to America" idiotic chanting. But you can be certain that it would be a very serious player on the world stage.
