The most explosive question about the Taliban resurgence here along the border between Afghanistan and Pakistan is this: Have Pakistani intelligence agencies been promoting the Islamic insurgency?
...
Hamid Gul, the former director general of Pakistani intelligence, remains a public and unapologetic supporter of the Taliban, visiting madrasas and speaking in support of jihad at graduation ceremonies.
Afghan intelligence officials recently produced a captured insurgent who said Mr. Gul facilitated his training and logistics through an office in the Pakistani town of Nowshera, in the North-West Frontier Province, west of the capital, Islamabad.
NATO and American officials in Afghanistan say there is also evidence of support from current midlevel Pakistani intelligence officials. Just how far up that support reaches remains in dispute.
