WASHINGTON  President Bush secretly approved orders in July that for the first time allow American Special Operations forces to carry out ground assaults inside Pakistan without the prior approval of the Pakistani government, according to senior American officials.

The classified orders signal a watershed for the Bush administration after nearly seven years of trying to work with Pakistan to combat the Taliban and Al Qaeda, and after months of high-level stalemate about how to challenge the militants’ increasingly secure base in Pakistan’s tribal areas.

American officials say that they will notify Pakistan when they conduct limited ground attacks like the Special Operations raid last Wednesday in a Pakistani village near the Afghanistan border, but that they will not ask for its permission.

“The situation in the tribal areas is not tolerable,” said a senior American official who, like others interviewed for this article, spoke on condition of anonymity because of the delicate nature of the missions. “We have to be more assertive. Orders have been issued.”
