The agreement that funded Iran's nuc program & relied on them to keep their word? Of course.

And it was never a treaty....Obama did it on his own because he couldn't get it through a congress that his Dem party controlled. Other Dems said "no" as well, in particular because they did not trust Iran. Nor did they trust the corrupted,inept, and anti-US UN to oversee Iran.

It was foolish, and it has resulted in Iran now having a nuclear program.

Btw, Biden/Harris just warned Israel not to strike back at their nuclear program or their oil production infrastructure (that which funds their wars).
Biden/Harris Adm also leaked Israeli retaliation plans on line as well - damaging our trust with all allies - esp Israel.

Unbelievably stupid...unless you are pro Islam/pro Iran...which they are at heart.
Of course, you know this Harris wouldn't even pick the best running mate Shapiro because he was Jewish.
