For some reason and all of the sudden Iran's nuclear program is a major concern, but for years during the Obama and Biden administrations (and even during Trump's first,) it wasn't. Whether Iran's nuclear program is seeking energy independence or weapons capability is open for debate, and from the perspective of most Americans, if of little concern.
irans NPT started in obama's era(2015) but was a 10 year contract.. do the math.. -> 2025. and you soon learn why iran has broke away from the terms of the NPT this year and now refusing to sign a new agreement.
instead they want a 15 year war where they want to annihilate isreal by 2040
