Watch part two
One of Barack Obama's biggest foreign policy challenges since he became president in January 2009 has been Afghanistan.
He calls it a war of necessity and has ordered the deployment of another 30,000 troops there.
Obama says the US military escalation is intended to deny al-Qaeda a safe haven and to reverse the Taliban's momentum.
As the conflict enters its ninth year, we look back at the initial weeks of the war through the perspective of a US military officer who led the first special forces team deep inside Taliban territory in 2001.
The men landed in Uruzgan province just weeks after the September 11 attacks and worked with a little-known tribal leader, Hamid Karzai, to disrupt the Taliban.
On Thursday's show, Anand Naidoo, who is sitting in for Riz Khan this week, talks to Major Jason Amerine, who led that operation, and Eric Blehm, who documented the mission in his book The Only Think Worth Dying For: How Eleven Green Berets Forged a New Afghanistan.
This episode of the Riz Khan show aired from Thursday, January 21, 2010
