"Why are we asking this now?

Nato and the US are ramping up the war on drugs in Afghanistan. American ground forces are set to help guard poppy eradication teams for the first time later this year, while Nato's defence ministers agreed to let their 50,000-strong force target heroin laboratories and smuggling networks.

Until now, going after drug lords and their labs was down to a small and secretive band of Afghan commandos, known as Taskforce 333, and their mentors from Britain's Special Boat Service. Eradicating poppy fields was the job of specially trained, but poorly resourced, police left to protect themselves from angry farmers. All that is set to change."
