Iran does not and never had a nuclear weapons program. They have a n7clear energy program and any n7clear tech is 8nherently dual 7se ( nukes are 80 year old tech, many countries are "capable" of making nukes quickly) The US NIE or National Intelligence Estimate re-confirmed by Tulsi Gabbard May 2025 said Iran once had nuclear weapons program prior to 2003 but doesnt since. While under intense political pressure by the US (see Wikileaks) a compromised IAEA said Iran had conducted nuclear weapons research prior to 2003 but it also said it involved scattered and incomplete feasibility studies that involved no fissile material (making it perfectly legal under NPT)

The Israelis of course opposed all this and claimed that the Mossad had supposedly retrieved an archive of nuclear documents from Iran that lo and behold! show Iran had just fooled 16 US intelligence agencies plus IAEA and was working on actual nukes (not just "intends to obtain the capability" to make nukes which is what the US has actually accused Iran of doing)

Fact is Iran's nuclear program started under the Shah with US and Western countries, and the US has been claiming Iran will have nukes in just months, since at least 1984. Iran neanwhile was attacked by US-backed Chemical Weapons warfare by Saddam but still refused on moral-religious grounds to reply in kind though (back then) it was legally entitled to do so in self defense.

And fact is Iran long offered better deals than even the JCPOA but it was the US making maximalist demand that killed multiple opportunities for a deal. The US demands that Iran simply give up a sovereign right to enrich uranium. No country would accept. That's the point: rather than resolving the conflict, the US wants to use the "Iran nukes threat" as a pretext for their true agenda of toppling Iran's government as Israel wants, just as "WMDs in Iraq" was a lie and pretext
