Iran was set to disclose their new nuclear capabilities and locations to the IAEA.
Netanyahu (with Trump support) did surprise bombings on Iran that day, starting the "12 day war" and Iran cancelled the disclosure.
It's that exact "hidden" plant that Netanyahu used as justification with Trump to start this current war.The claim was that they had a hidden nuclear facility they were hiding, and that it MUST be malicious since they won't reveal it. The problem is, they had been planning to.
This is why the Congress 'Gang of 8' said there was "no evidence of imminent threat" when briefed on the cause of this war.The very program they are fearmongering about, was one Iran was set to disclose.
And right now, we have NO IDEA where this facility is, and the 11+ ton stockpile of uranium because we believe it MAY attach to the Isfahan facility, but intelligence suggests its a different facility even DEEPER in the mountain complex.
