It seems that the homepage editor of the New York Times made a Freudian slip here:

Cut from a screenshot of the current NYT Global homepage
The link for the "U.S. Agency …" headline goes to a piece headlined Nuclear Agency Resumes Talks With Iran Over Access to Sites:
LONDON β Senior inspectors from the United Nations nuclear watchdog renewed talks with Iran on Friday aimed at securing access to restricted sites where the agency believes scientists may have tested explosives that could be used as triggers for nuclear warheads, officials at the agency said.
The discussions at the International Atomic Energy Agency in Vienna …
To name the IAEA an U.S. agency, when it is supposed to be an independent technical agency associated with the United Nations, is not completely wrong. As we know from Wikileaks cables the head of the IAEA, Yukiya Amano, is a total U.S.puppet:
Amano reminded [the] ambassador on several occasions that he would need to make concessions to the G-77 [the developing countries group], which correctly required him to be fair-minded and independent, but that he was solidly in the U.S. court on every key strategic decision, from high-level personnel appointments to the handling of Iran's alleged nuclear weapons program.
The homepage editor's slip was probably induced by that and as such simply documented the truth about the IAEA in its current form.
The whole nuclear weapon issue with Iran is of course not about anything nuclear as Iran has no nuclear weapons program. It is about continued U.S. hegemony over the Middle East which requires regime change in Iran. The recent negotiation offer to Iran was not serious and now the P3+3 talks are again getting stalled by the U.S./EU side. The Obama administration does not want to find a solution with Iran. For now it wants to push the issue off until the U.S. election is over. If the economy allows the U.S. then may again push for war in the following year.
