Is that why the regime had to shut down the internet for 3 weeks, and kill 3K people and injure 25K people (per their own official statistics) in just 2 days to suppress the pro-Pahlavi protests? lol Like it or not, Pahlavi is by far the most popular choice. He has millions of supporters inside and outside Iran.
People hate the IRGC right now. If you think after January protests, people will support the IRGC, you are wrong. Majority of Iranians are waiting for the US to bomb Iran. You just need to talk to Iranians on Instagram, YouTube, reddit, X, or even your co-workers. They are even calling for the US to take action against the regime in Iran and you think Iranians want the IRGC to continue their plundering of our wealth for the Arabs in Palestine and Lebanon? You can't mean that.
There is no balkanization of Iran at this point. If anything, I would be afraid of the Balkanization of Iran by a regime that has always prioritized Islam and Arabs over national interests of Iran.
