they were cheating from the get go.they never allowed inspections on military sites. they have a vast underground development area that's off limits.Trump broke the deal. The Iranians should be praised for maintaining their own word for so long. They are more than entitled to do what they like with their own nuclear development- stupid though that is- while Biden continues with Trump's moronic sanctions and give his idiotic blanket support to the most dangerous nuclear-armed state on earth.
The deal was bad. it didnt address their terrorism / hegemony or ballistic missiles and only delayed "breakout"
sanctions didnt work because EU and China dont want them to work.
Best just to consider Iran a funding of state terrorism.
We missed a big chance on the Green Wave of Iran to stand with the protesters in the streets
