Watch part two

On Friday, Barack Obama, the US president, made a case for expanding the war in Afghanistan and called the situation there "increasingly perilous".

He said he was setting new benchmarks and sending in 4,000 more troops, hundreds of civilians and increased aid for a six-year war that has no end in sight.

Obama defended his strategy, warning that al-Qaeda is actively planning attacks on the US and that the goal was "to disrupt, dismantle and defeat al-Qaeda in Pakistan and Afghanistan, and to prevent their return to either country in the future".

On the next Riz Khan show we discuss Obama's new plan for Afghanistan and ask: Can he deliver?

Joining the programme will be: Robert Greenwald, a filmmaker and political activist who is working on a documentary on Afghanistan.

He has just returned from Afghanistan and says "a policy involving a surge of 21,000 teachers, doctors and sanitation workers would be far wiser than a policy of 21,000 more troops".

Riz also talks to Barmak Pazhwak, an international development specialist at the US Institute of Peace, and Lisa Curtis, a senior research fellow at The Heritage Foundation.

This episode of Riz Khan aired on Monday, March 30, 2009.
