I dont know. I am not a nuclear scientist. All I can say is that military or civilian, a sovereign nation has a right to pursue whatever research/development they want to do. But yes they shouldn't have signed the CTBT and NPT like Israel, India and Pakistan.
But that said, there is a lot of double standards in the way the west treats Israel vs other muslim nations. And the supporters of this relationship have the tried and tested "antisemitic" accusations ready and primed to lob at you to silence you. How criticizing Israel, a multi-religious, multi-ethnic country, and its policies, can be specifically antisemitic is beyond me.
You're right about the double standard. I don't see much complaining about Pakistan being a non-NPT nuclear power. Meanwhile Iran is an NPT signatory that is enriching to 60% and refuses to answer IAEA questions about apparent NPT violations.
You might want to claim ignorance as a way to ignore the reason why the UN is currently concerned about Iran's program so I'll help you out.
U-235 enriched to 3.67% is commonly used as fuel for a reactor. Small amounts of U-235 enriched to 19.75% can be used for medical isotopes.
There is no civilian justification for Uranium enriched to 60%. Its only use is either as a step to 90% enrichment or a threat that they can do it if they want.
The other issue identified by the UN is their enrichment capacity. Because of lack of IAEA access, we don't know the exact extent of Iran's centrifuge program but last reports had them with with similar enrichment capacity as the US despite having only one civilian reactor.
p.s. the only reason anti-semitism was brought up was because Franky claimed Israel is controlling US policy.
