“... without hurting or targeting civilians, bomb and take out Iran’s nuclear sites.”
This is naive & simplistic, at best. No surgical strike on Iranian nuclear facilities can hope to succeed on its own.
Iran is not without means to defend itself. Bombers cannot simply fly in & bomb without first destroying Iranian air defenses. An intense, weeks long campaign to destroy these defenses is required.
Iran is not going to sit by quietly while the US bombs it. They are going to attack any US targets in the area with every weapon at their disposal. Those targets include US Navy vessels, commercial tankers & cargo ships, US bases in the area, etc. Any attack on Iran must destroy these offensive weapons ASAP.
In both these efforts it would be dangerously foolish to try to minimize civilian casualties. Iranian defenses & offensive weapons must be thoroughly destroyed regardless of close proximity to civilians.
On the contrary, to “win” this war a lot of civilians need killing, starting with the entire Iranian government, all the nuclear scientists & their employees, & all terrorist sponsoring groups.
Only after the Iranian military is thoroughly beaten down can the US then begin the process of destroying the Iranian nuclear program. But once sufficiently bombed, US troops & inspectors will still be needed to verify the destruction. That entails a ground invasion.
So, the only sure way to end the Iranian nuclear program is with a war like we waged against Iraq. Bomb Iran to rubble, destroy its military, invade the country, arrest/kill its leaders, & completely destroy its ability to threaten anyone for a long time. I favor a long occupation of the country with permanent military bases established there to preclude a resurgence of Shia radicalism. I would also take Iranian oil to pay for our long term effort. They caused the war, they can pay for it. In the end, it will have been money they well spent to rid themselves of the mullahs.
But, there is a problem, a big one: Iran’s ally Russia.
It’s very clear that a surgical strike now would cause far less damage than after the monster has been allowed to grow. Potshot retaliations instead of all out war later is something that I’d count on, but would be worth it a thousand times over.
