You know U.S. actually did fund militant groups directly a few times because we thought we can make it a better place. In fact that’s how big, powerful complicated militant groups started to rise in the Middle East and they are out of control now.
Not to mention, that is kind of still on going with all the support to Saudi Arabia.
When it comes to Iran,
1953, U.S. and UK did overthrow the democratically elected Prime Minister of Iran only because his interests wasn’t aligned with ours!
Before that, During the WWII, British and Russians invaded Iran and did overthrow Iranian king because he was neutral and we needed their oil fields.
And then revolution happened in Iran and this time people did overthrow the last King who was introducing many social, economic, and political reforms in Iran but we hated him because he was moving too fast for our interests. (Skipping some conspiracy theories about how CIA did trigger the revolution by turning people against the king)
And then Iraq/Saddam Hossein(Yes! Same guy that U.S. killed after the U.S. invasion of Iraq) was supported directly, intelligence and military, by the U.S. to invade Iran as a counterbalance to post-revolutionary Iran. Which took them 8 years and it was one of the deadliest conventional war ever fought in modern history, and both countries never recovered from it.
And that’s my friend every single man/government they had in power since 1940. So no wonder why it’s so fucked up in Middle East now.
Every single time we thought we can make it a better place, But there are consequences to foreign interventions that we can’t control. One of the the richest regions in the world in terms of natural resources and history consequently is in complete misery as a result.
