This is pure scapegoating. The Iranian society is extremely prejudiced against Afghani people, who have been systematically put into the same class as women in the Iranian state: second class humans. Not even citizens, as many second and third Gen immigrants still can't receive citizenship.
Israel is commiting a genocide, Iran uses this as a pretense to ramp up oppression and strengthen its grip on its people.
So Business as usual!
Denn nie wieder gilt nur dann, wenns für uns nicht mehr profitabel ist.
