While Iranian officials have described the poisoning as a deliberate criminal act, the Islamic Republic has failed to take action to protect Iranian girls and bring to justice those responsible. This alone would amount to dereliction of duty, but worse still, the fact that women and girls have been the target of the ongoing crackdowns brings the government's own possible role into question. The international community must hold an external investigation.
By launching a criminal investigation into these disgraceful attacks against schoolgirls, the Islamic Republic of Iran has demonstrated its commitment to encouraging Iranian girls to study, work, and think in a safe environment in order to become protagonists of the nation's progress. It is nonsensical and malevolent to try to blame Tehran for such incidents.
There's a 50% chance that Iran will cease to be an Islamic Republic by January 2036, according to the Metaculus prediction community.
