While folks here are quick to jump to blaming the US for this, it's also worth noting that the US is the one that has been enforcing international order so far. So it gives us a bit of a glimpse of what would the world would look like with a more isolationist US, or a multipolar world.
>the US is the one that has been enforcing international order so far. I'd be with you here if the US CIA wasn't the one who overthrown the democratically elected Mosaddegh and replaced him with their puppet Shah, triggering the Islamic revolution. But I'll give you a pass since I heard they don't teach this part in american public school history curriculum.
It's just as ignorant to cherry pick one event in the history of Iran as the source of all it's problems as it is to say Americans don't know their own history. It's not that simple.
