Pakistan's campaign in southern Waziristan, against Taliban threatening the integrity of their state, has been successful, in part. The Taliban of North Waziristan, fuelling the insurgency in Afghanistan, remain untouched. News is threading through of redeployment by the insurgents to Orakzai, near Peshawar, and a direct threat to NATO supply lines.
The question of Pakistani fragmentation and the consequences for the nuclear arsenal are rarely aired in public. Even if they are, bland assurances of current security are given, leaving detailed assessments of the security threat in private. Pakistan is a radioactively hot topic.
