"Arms Control Wonk" Jeffrey Lewis claims in Foreign Policy:
There was nothing new in Netanyahu’s presentation ... Moreover, the archive contains little or no information that wasn’t already available to the IAEA and the rest of the world at the time the JCPOA was signed. ... As a result, Netanyahu’s description of Iran’s pre-2003 nuclear weapons program — and let’s be clear, this is historical material — contains no new revelations that have not already been detailed by the IAEA in its final report on Iran’s nuclear weapons program, “Final Assessment on Past and Present Outstanding Issues regarding Iran’s Nuclear Programme.” You know, the one that concluded Iran had a “coordinated effort” to conduct “a range of activities relevant to the development of a nuclear explosive device” — that is, a nuclear weapons program.
This refers to Benjamin Netanyahu presentation about Iran's nuclear program, given on 30.4.18. I sorta doubt this claim - no new substantial information - because many commentators treat the presentation as a smoking gun.
Here's one critizism of the claim "nothing new", in the Times of Israel:
Netanyahu’s critics further assert that there was nothing new in the material he presented — nothing new in the showcasing of Iran’s own evidence of its deceit, and of the specifics of its nuclear weapons program. First of all, that criticism is patently false. The International Atomic Energy Agency, in its own reporting, has never claimed to have attained remotely comparable access to Iran’s own documentation. The Mossad spirited out 100,000 files. The P5+1 negotiators should race to pore over the material.
From this, though, it appears that the only "new" information is the existence of a nuclear weapon program pre-2003.
