alt Hacker News... and then, of course, we switch moral fallacies. The supposed superiority of doing nothing. Hope you never need an ambulance, because of course, clearly, according to your reasoning the moral action would be to let you die.
And btw: your motivation, obviously that you want Iran hardliners to win inside Iran, is showing. Carefully placing the blame for the actions of the hardliners with the US. Needless to say, that is not a moral position at all.
There's many problems. First: every agent with agency is of course responsible for their own actions. Which means Iran's regime, islamists and islamic clergy are despicable monsters because of what they did.
That there is a reason they did what they did does not explain their actions in any moral sense. It makes it worse, of course. It means that they're indeed fully responsible for their actions, that they're not insane, made a choice, and their choice shows them to be truly despicable, immoral and disgusting human beings.
You are conflating "doing something" with "doing something useful".
The US could have chosen not to kill the supreme leader (who was the only one able to drive a change), a large part of the moderates in the government and negociators.
It could have chosen to send other people than crooked incompetent real estate managers to negotiate with Iranians about complex nuclear issues.
It could have chosen to propose an acceptable plan to Iranians that allowed room for negotiation, not just a blanket capitulation and surrender.
Your view of foreign policy is immature, similar to a child trying to wash the dishes and breaking them as he does. When the parents arrive, he cries and says "but I'm trying to help!".
And I don't like the IRGC but I also would prefer to avoid the humanitarian and refugee crisis and civil war in a 90M pop country. Which will happen after the US "liberates" them by bombing civilian infrastructure such as water treatment or electricity plants. Did they ever say "thank you"?
Because I know that others will pick up the pieces after the US and Israeli meatheads in power will come back home. Just like it happened in Irak, Syria, and Lybia.
