No, U.S. Doesn't Have 'Absolute Knowledge' on Iran's Nukes

Contrary to the contention of Secretary of State John Kerry, leading lawmakers and other experts tell us the U.S. intelligence community does not have "absolute knowledge" about past military aspects of Iran's nuclear program.

During a video conference with reporters Tuesday, Kerry was asked whether Iran had to address outstanding questions about past nuclear weapons work from the International Atomic Energy Agency as a condition for the West lifting or easing sanctions.
