No, I don't need a history lesson. Yes, you are right, they got in following a protest vote by the people rejecting the corrupt regime of the Shah, that is true. However, they didn't know what it would lead to, and now in the 2020s, you know full well they want them out, as do all decent Iranians. They are kept there with their vile ideology through force and with the help of the IRGC. You KNOW this. The Islamic Revolutionary Guard Corps (IRGC). This is arguably the most important pillar. The IRGC is a powerful military, intelligence, and economic organization that answers directly to the Supreme Leader rather than the elected government. It also oversees the Basij militia, which has often been used to suppress protests and maintain internal security.
