The Wikileaks revelations about murderous collusion between Pakistan's Inter-Services Intelligence (ISI) agency and the Afghan Taliban have underlined the central role that country plays in the sponsorship of terrorism. This is despite the US disbursing $1 billion a year to enable the Pakistanis to fight it. In this respect, it would seem that enemies like Iran or Syria are a secondary problem.
And the collusion goes far beyond corrupt and dozy Pakistani border guards turning a blind eye to the Taliban launching cross-border raids on coalition troops in Afghanistan. It also means ISI involvement in planning the insurgents' operations, as well as even more murky links alleged between ISI figures and mysterious "Arabs". That's the preferred synonym, by the way, for members of al-Qaeda, who are embedded with the Haqqani and Hekmatyar networks, which the ISI once sponsored to fight the Soviet invasion.
