The source for this article is a WorldNetDaily post from 2005. It was as preposterous and unsourced then as it is now. We face real threats from radical Islamists, but there is no sense in conflating them into an apocalyptic nuclear scenario for which there is presently no scientific or intelligence support.
This article is bogus, but it actually makes sense that the reason we haven’t heard from bin Laden lately is that he is concentrating on getting nuclear weapons and on striking a more decisive blow than on September 11th.
