It's never easy to make documentaries in Pakistan - especially for journalists who, like those on Panorama, aren't based there.

Given the startling access Jane Corbin and her cameraman/producer Nikki Millard got - not only to the troubled areas around Peshawar, but also to the Pakistan army's battles with militants linked to al-Qaeda and the Taleban in the tribal areas - the new civilian government at least appears serious about showing (some) of what it's up to.

And, despite a war of words over the Americans' use of Predator drones to target militant bases in these areas, Pakistan's efforts have so far been welcomed by many in the US. And that matters. President-elect Obama has made a great deal out of promising to shift the focus of the "War on Terror" to Afghanistan.

Many are sceptical that he can pull off what will be one of the biggest issues of his administration. So both Washington and London will be exerting maximum pressure to ensure that future troop deployments won't be undermined by a porous Afghan-Pakistan border and an ambivalent Pakistani government.

Just how damaging this ambivalence has been in the recent past is eye-poppingly chronicled in this, highly-influential book. None of which makes the job of reporting or filming there any easier.

Jane and Nikki took sizeable, if considered, risks in getting some of their footage. They arrived in Peshawar - already a very tense city - on the day an American aid worker was shot dead and an Iranian diplomat kidnapped.

There are regular threats to Western journalists in Kabul too. So there had to be a clear reason to take such risks. The title, Britain's Terror Heartland, gets to the nub of it. Obtuse - even provocative - perhaps, but the facts and figures bear it out.

Separately, Gordon Brown stressed this on Sunday. British security services are believed to be monitoring some 2,000 individuals - and an estimated 30 active terror plots - the majority connected to Pakistan in some way.

Perhaps as a consequence, we also had to obscure or drop the identity of at least one person in the film for legal reasons. This will be a sensitive, challenging, subject for a long time to come.
