IRI is the acronym for Iran's official name, Islamic Republic of Iran. I'm reading this as Iran is in control of Iran's Revolutionary Guard. What are you referring to exactly in your first sentence?
First of all, the I in IRGC stands for Islamic and not Iran. In fact, neither their logo or any of their patches mentions the word IRAN.
As my beloved homeland is, imo, under effective coercive occupation of Islamist ideologues (there is not a even hint of godliness in that regime) it is preferred that you refer to the regime by its name IRI and not cast calumny on the beauty that is IRAN.
The name of the IRGC was not the part of your original comment that I was questioning, but your use of IRI. Did you mean to say that the IRI is no longer in control of the IRGC?
