Who knows? I would think that after the failure of the European and American (before Trump’s withdrawal) signatories to adhere to their part of the JCPOA which stipulated that Iran must reduce it's uranium stockpile (in terms of sanction relief etc). Iran stopped complying too hence the stockpile.
Now though after the unprovoked attack, I imagine that there will be debate in Iran over going the Libya route or North Korean route.
The result is that thanks to this misadventure, no one knows where the 400kg of uranium is and the NPT and IAEA have been severely undermined.
There will be several countries now secretly working towards to proliferation to protect their sovereignty.
