Dictators are established when someone is attacking or meddling in a country, which UK and US were genuinely doing from 1950s till now in Iran.

Current government is a product of western actions in Iran.

It’s short sighted. If in 1950s they left Iran alone, the IRGC would disappear a long time ago because their strong grip would not be needed nor justified.

But every western leader wants to record a win, and constant attacks further increases the required grip of the IRGC.

Can even go back another 100 years of Imperialist England and Russia fucking over Iran. With the current regime being a result of the 50's coup that were a result of BP/England wanting to keep most profits of oil, which they had done since early 1900s.
