You are wrong[0], see Khorramshahr. Maybe Iran found ways to make them more easily produced. And there are videos where you can see missiles splitting into other missiles, some of which go in different directions.
As before, it's Apartheid Israel that uses cluster bombs (and white phosphorus too).
You are wrong if you think Iran is targeting each sub-munition of the ballistic missiles it is firing at Israel civilians. No country has ever used any ballistic missiles that has conventional MIRVs because it simply doesn't make sense.
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.
