Iran is less expansionist, more "Everyone around us hates us and America hates us, so we can only preserve ourselves only by preemptively making them 'friendly'". Even Safavid Persia stopped expanding after its peak, following which the only time it went expansionist was under Nadir Shah. The "us vs the world" mentality grants the theocratic regime legitimacy. The Iran-Iraq war (Saddam's mad campaign in other words) did not help in soothing this mentality either - it still remains in recent memory for many Iranians.

The rest are of course expansionist.
