It's not particularly easy to tell facilities for making enriched uranium (viable as fuel) from facilities making weapons-grade HEU.

Iran was proudly announcing enriching over 60%, which is the highest amount anyone, anywhere, ever, needs to do (60% is for neutron-optimized research reactors).
Non signers get no access to any technology or know-how from signers but are free to act as they please. Israel, Pakistan and India all fall into this category. They can act as they please.
Oh is that how it works...
1. US law provides for ratified treaties to have the same force as federal law (https://en.wikipedia.org/wiki/Treaty_Clause) 2. The US and Iran have both ratified the NPT 3. The NPT guarantees the rights of signatories to establish peaceful nuclear programs 4. It's therefore, in theory, illegal under US federal law (which of course, at least applies to US persons) to interfere with the establishment of a peaceful Iranian nuclear program.
The practice of course, differs greatly from the theory. This is because, as per usual, law is more about politics than law.
Iran is a sovereign nation. The US signing a treaty has no bearing on them unless they sign it too.
