A week after President Obama announced the time line for withdrawing troops from Afghanistan, his top counter-terrorism adviser, John Brennan, says the US war on al-Qaida is far from over.

Eric Schmitt, senior writer and terrorism correspondent for The New York Times, talks with us about this shift in strategy.
