An article from 1995 reveals that Benjamin Netanyahu stated that Iran would be in possession of nuclear weapons by around 2000:
"Within three to five years, we can assume that Iran will become autonomous in its ability to develop and produce a nuclear bomb, without having to import either the technology or the material.
[The nuclear threat] must be uprooted by an international front headed by the US. It necessitates economic sanctions on Iran."
Some things never change!
