What is a better outcome in your mind? If this base wasn't bombed, it would continue attacking Iran, so the total amount of bombing would increase. Should they ask them to stop through diplomacy? USA cancelled a scheduled negotiation to launch the attack. But you still think they would be willing to stop the attack with nothing in return? Would USA pay reparations for the people they already killed? Should Iran have offered something to appease the attacker? Even if they had stopped for free, that would've been in essence paying with the lives of those the USA murdered. Do you think that would be a good outcome?
