Dispatches Afghanistan Mission Impossible

As war in Afghanistan persists and British soldiers continue to lose
their lives fighting an insurgency that many commentators say they
can't defeat, reporter Stephen Grey investigates whether our military
is engaged in an impossible mission.

In an unprecedented series of interviews, senior military commanders -
including Air Chief Marshal Sir Jock Stirrup, chief of the defense
staff, and General Sir Richard Dannatt, chief of the general staff -
reveal what they think of the successes, failures and lessons learned
during Britain's three-year intervention into Helmand province.
