we currently have the capacity to destroy Iran's military and industrial capacity at a tiny cost to ourselves.
I think you're underestimating Iran's defences.
At the present time, with Natanz's plant fully bunkered, there's no way to disable it and the couple of other support plants with a surgical attack. If you want to disable Iran's nuclear capacity (not even considering its military or industrial facilities) you need to go heavy tactical or nuclear, which will mean full scale war (ugliness ensues).
Besides, international sanctions were much more effective at destroying Iran's economy, which is the only reason why they accepted the terms under the present treaty.
The current deal will lift international sanctions. The Massive Ordnance Penetrator bomb might be able to destroy any of Iran's nuclear plants.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
