Former US Secretary of State Anthony Blinken on Iran:
The thing that President Trump chose, military action, I think again was a mistake, because every previous administration has looked at it and decided that it really should be a last resort.
Even if you do that, you can get Iran back for a short while, but really you'll likely only get a few years of setback.
The plan will be buried deeper underground, and they will come back and do even more.
