From Semafor (below) that confirms that when unofficial negotiations between Biden’s team and Iran collapsed, U.S. officials cited Iran’s refusal to cooperate on UN nuclear inspections. Specifically, Iran resisted addressing uranium traces found at undeclared sites and blocked International Atomic Energy Agency (IAEA) inspectors. This lack of transparency led Western nations to pass a censure resolution against Iran at the IAEA.

So yea, I guess if you turn a blind eye to someone not honoring the deal you can pretend the deal is a great success. It's like your wife cheating on you and pretending like you don't know about it so you can say you have a healthy marriage to others.
By the way, life comes at you fast and progress enables speed. What took a year in Obama's day to enrich the uranimum and make a nuke, they can now do in days and since Trump's election they've gone from enriching 16 lbs of uranium per month to 75 lbs (and apparently for civilian use you only need a fraction of that, so clearly they are building)
