From the U.S. Embassy in Caracas, a great quote:
A plain-spoken nuclear physicist told Econoff that those spreading rumors that Venezuela is helping third countries (i.e. Iran) develop atomic bombs "are full of (expletive)." He said Venezuela is currently unable to provide such assistance particularly as the Chavez administration "does not trust scientists."
Interestingly, this is rather like the long cable on Honduras, where diplomats contradict extravagant claims yet are mostly ignored.
