Pakistan also agreed to move 6,000 troops from its Indian border to fight militants on its western border with Afghanistan, according to a Pakistani official who did not want to be identified discussing troop movements in advance.

But American officials, who welcomed the redeployment, said Pakistan was still not doing enough to fight the insurgents, who are tightening their hold on the country. The Americans expressed frustration that Pakistan was still rebuffing their offers to train more Pakistanis to fight Al Qaeda and the Taliban…

“It is reasonable for Pakistanis and Americans alike to ask why there has not been a more robust, sustained and serious response to elements that assassinated Benazir Bhutto, blew up the Marriott Hotel, attacked a visiting cricket team and assaulted a police academy,” the official said, ticking off a series of violent events that began with the killing of the former prime minister. He said it was “inexplicable” that the incidents had not “galvanized the Pakistani military and civilian leaders to link arms in a comprehensive, sustained campaign to fight back.”
