As before, it's Apartheid Israel that uses cluster bombs (and white phosphorus too).
Iran is far more of an apartheid state because Jews are considered to be Dhimmis and officially discriminated against. Dhimmi status is not equality. Recognized-minority status under the 1979 constitution comes with hard ceilings: Jews cannot hold senior military, judicial, or executive positions; inheritance law historically favored any family member who converted to Islam (a Jew converting could inherit the entire estate from Jewish relatives, a direct incentive structure against the community); testimony of non-Muslims is weighted less in court; blood money (diyya) was unequal until reforms in the 2000s. The reserved Majles seat is one out of 290, tokenism, not representation.
