With the United States facing the reality that its broad security partnership with Pakistan is over, American officials are seeking to salvage a more limited counterterrorism alliance that they acknowledge will complicate their ability to launch attacks against extremists and move supplies into Afghanistan.

The United States will be forced to restrict drone strikes, limit the number of its spies and soldiers on the ground and spend more to transport supplies through Pakistan to allied troops in Afghanistan, American and Pakistani officials said. United States aid to Pakistan will also be reduced sharply, they said…

American officials say that the relationship will endure in some form, but that the contours will not be clear until Pakistan completes its wide-ranging review in the coming weeks.
