You're conflating decades of failed nation-building with a fundamentally different situation. No one is talking about occupying Iran, installing a puppet government, or repeating the Iraq playbook. The conversation is about whether the world can tolerate a regime that has directly funded Hamas, Hezbollah, the Houthis, and repeated attacks on American forces and Israeli civilians — while actively pursuing nuclear weapons.
Your historical examples are worth taking seriously, but they actually cut both ways. Many of those failures stemmed from unclear objectives, poor post-conflict planning, and half-measures that created power vacuums. The argument isn't to repeat those mistakes — it's to not pretend that inaction is automatically the safer choice. Iran is not a stable status quo. It is an actively destabilizing force across the entire region.
It's also worth noting that the Iranian people themselves are not the regime. They've risen up repeatedly — in 2009, 2019, 2022 — and been met with brutal crackdowns. The mullahs do not represent the Iranian population any more than the Taliban represents Afghans.
The concern about blowback is legitimate and shouldn't be dismissed. But the alternative — a nuclear-threshold Iran with an unbroken funding pipeline to terror proxies — carries its own catastrophic risks. The question isn't whether there's risk. It's which risks are more manageable.
