Prime Minister Binyamin Netanyahu said, Monday evening, that Israel had obtained Iranian archival material showing five key elements of a nuclear weapons program.
Outlining three of those elements, he presented "an original Iranian illustration of a weapon", "a photo showing the casting process and a cast metal core, from the archives. And here’s a secret underground facility the Iranians were building to produce nuclear cores" and "an original Iranian photo of a measuring device for implosions. And here’s a simulation of a nuclear implosion."
