This week the Associated Press reported that unnamed officials
"from a country critical of Iran's nuclear program" leaked an
illustration to demonstrate that "Iranian scientists have run computer simulations for a nuclear weapon
that would produce more than triple the explosive force of the World
War II bomb that destroyed Hiroshima." The article stated that these
officials provided the undated diagram "to bolster their arguments that
Iran's nuclear program must be halted."
The graphic has not yet been authenticated; however, even if authentic, it would not qualify as proof
of a nuclear weapons program. Besides the issue of authenticity, the
diagram features quite a massive error, which is unlikely to have been
made by research scientists working at a national level.
