> we should have let Iran have nukes?

What part of this war has made Iran less likely to get a nuclear weapon?

There could have been a good war in Iran. A coalition of nations going in to secure the uranium. It would have been messy. But it would have had a clean objective.

As objective yes but whose lives would be spared for this objective? Messy is relative to policies. Aren't other ways to attain this objective other than through war? I really think there were attempts and progress in that direction.
