Interview: Extra troops for Afghanistan?

President Barack Obama is expected to make an announcement on a troop surge in Afghanistan on Tuesday, while the New York Times is reporting that allies are being hit up for an extra 10,000 soldiers. 

I asked the Lowy Institute's Andrew Shearer — who has been involved in managing Australian coalition troop contributions both at the Australian Embassy in Washington and in Canberra — about the announcements. You can listen to his response in the audio track below.
