It was one of the more surreal photo ops this week: Iran's president Mahmoud Ahmadinejad, live on Iranian TV, visiting a nuclear reactor. Ahmadinejad trumpeted his country's nuclear progress, but denied, once again, that Iran is pursuing nuclear weapons.
In Washington, officials weren't buying it.
They rushed to repeat the official U.S. line — a line President Obama himself is fond of delivering.
"Let there be no doubt: America is determined to prevent Iran from getting a nuclear weapon, and I will take no options off the table to achieve that goal," he said.
