As opposed to standing idly by when the regime 'stabilizes' the country by murdering thousands of people? It's well past the stage where non violent protest or resistance stopped being a viable option..
Do you demand an invasion of Israel? Because your moral principles seem to demand an invasion and subjugation of Israel.
There is absolutely no requirement for consistency in geopolitics. Advocating for a position on e.g. Gaza or Iran isn't undermined because that person isn't expending equal efforts on injustice in another theatre.
There is in morality, though. The US is a state, but you are a person.
The problem with your stance is that too many people want it both ways: They don't want the US to intervene, but then also want support in terms of money and special treatment for people emigrating from these countries (and blame the US for the deaths that occur for a terrible government).
There were almost no Syrian refugees before operation Timber-Sycamore. Thank you USA, our dear friend and freedom-sharing soulmate, for unnecessary refugee crisis in Europe (and another one from Ukraine). With friends like that, who needs enemies. Also, as the above two examples (and Biden's Inflation reduction act, and Nuland's 'f*k Europe'), it is not a Trump thing, its USA thing.
What special treatment are you talking about, really.
And all while making "death to america" part of their national slogan.
Africa is tricky due to historical reasons, though. Any western power that would intervene there without the explicit invitation of the local government would be accused of neo-colonialism etc.
Do you really believe that after the violent regime change Iran will become the beacon of prosperity in the ME?
Yes, I believe if the things are really out of hands (like Khmer rouge in Kambodia), external intervention is warranted.
That can be done against small/weak states where the result can be achieved fast and without too much bloodshed (compared to what is already going on), and when agreed on by UN. Will most definitely need boots on the ground.
It is an entirely different matter against a 90million vast state like Iran. Note that boots on the ground is not in the cards, and most probably will never be. The approach is 'bomb and hope'. Which guarantees misery and bloodshed of Iranian blood. And if the result is fall of the ayatollah regime, and replaced by nationalists with socialistic tendencies, that would not really cooperate with USA (= sell oil rights and totally dismantle their military) then what? Bomb more? How can you honestly believe this is the best for Iranian people?
