I'm probably wrong, but what happened after WW1?
Wasn't Iran "formed" then, along with Kuwait, Iraq, Syria, etc.?
No!
Iran (Persian) has never been colonized or ruled by foreign governments.
Those countries including Syria, Jordan, Saudi, Kuwait, Iraq... etc were part of the Ottoman empire and later with the help of the Brits these countries were formed as nation-states.
Iran has always been independent and free of foreign ruling
