You don't think Iran's situation is also mostly its own doing?
No, you see the instant a western power interferes with a region, all agency is immediately stripped from every single person there. It's really sad, they all become puppets or automatons reacting purely to external stimulus.
The number of countries messing around in that region is long....
From the US, Russia and china to local powers like Israel, Saudi Arabia, UAE and Iran themselves.
Either you're a scholar studying the region, if not your comment feels naive at best
I personally am not well read on this, but I know lot of people blame the US and the UK since after they overthrew the democratically elected socialist government and installed a brutal dictator[0], the only elements that survived to oppose the dictatorship were hardened islamists, who later took power from the US backed Shah[1]

A key motive was to protect British oil interests in Iran after Mossadegh nationalized and refused to concede to western oil demands.
