Maybe some loud public criticism is exactly what President Barack Obama needs to distract from his failed Olympic bid. In the latest public admission in a nuanced debate over whether Iran acted appropriately regarding the development of its nuclear facility near the city of Qom, Iranian President Mahmoud Ahmadinejad says that Iran divulged facts about its nuclear facility early and that Obama was wrong to say that it didn’t. "The U.S. president made a big and historic mistake," said Ahmadinejad on Saturday. The debate over when Iran should have revealed its nuclear site is twofold: Both the IAEA and the U.S. say the country should have announced plans as soon as they existed; Iran says that according to protocol, it was not obligated to alert the U.N. until six months before bringing “nuclear material” into the machines, which it did. IAEA head Mohamed ElBaradei arrived in Iran today to set up the U.N. inspection of the facility, which Iran agreed to last week.
