They were under zero obligations after that deal sunset.

And they were under zero obligations once Trump abrogated the deal. Which is why they went from well under even the level of low enrichment for inefficient weapons to getting to that two-week breakout time frame. All breaking the deal did was put us immediately into the sunset that you're so worried about, as far as Iran's obligations were concerned.

Oh, and also the reason I brought it up - it showed that Trump cannot be relied upon to honor agreements. So the offer of enriched uranium for their nuclear power was never going to work, because there's no way that Iran could count on it being honored.

We’ve done more to knock back their ballistic missiles production than anything in the last 40 years already.

So? Once the war ends, they'll be able to rebuild that ballistic missile production. They've got a fairly substantial industrial base to their economy overall, so you're not getting much strategic benefit from doing this.

Have they, now.

Yes, they have.
