But at the same time, this war may have allowed IRGC to dig in. They've replaced a few people but the system may be stronger. Never mind that it doesn't even seem to be the administration's communicated goal to destroy IRGC in the first place.

On top of all that, they've threatened to reduce the entire country to the "stone age", and have started to target civilian industries.[0] If this campaign continues, how is this anything less than mass murder?

They're not doing this war for the reason you seem to want. They're not doing this to save Iranians.

Second order consequences can be a real sonofabitch, and history has shown that to be doubly true in the Middle East

How many civilian deaths as the direct result of US/Israel action do you consider acceptable to achieve killing the unelected murderers? 150 school children? Wikipedia cites hundreds more civilian deaths, but I don't know what sources to believe. How many layers of the regime's onion do we have to peel before we know we got all the murderers? How many children are we going to radicalize into future unelected murderers by murdering their family members and plunging their region into worse chaos? Should we kill 'em all and let God sort 'em out? Hegseth has crusader tattoos. Is he just another unelected theocratic murderer of a different stripe? Are we the baddies?

HRANA says thousands civilians dead. At least ~250 children. They are a reliable Iranian opposition source.

Now do putin and bibi next, and maybe Xi will realize taking other people's land by murdering is unacceptable and won't invade Taiwan.
