President Obama's Secret: Only 100 al Qaeda Now in Afghanistan
ABC News

"A senior U.S. intelligence official told ABCNews.com the approximate estimate of 100 al Qaeda members left in Afghanistan reflects the conclusion of American intelligence agencies and the Defense Department.

"With 100,000 troops in Afghanistan at an estimated yearly cost of $30 billion, it means that for every one al Qaeda fighter, the U.S. will commit 1,000 troops and $300 million a year.

"At a Senate hearing, the former CIA Pakistan station chief, Bob Grenier, testified al Qaeda had already been defeated in Afghanistan.

'So in terms of 'in Afghanistan,' asked Sen. John Kerry, D-Mass., 'they have been disrupted and dismantled and defeated. They're not in Afghanistan, correct?'

'That's true,' replied Grenier."
