U.S., Pakistan must heal relationship, Sen. Kerry says

Islamabad, Pakistan (CNN) - The United States need not apologize to Pakistan for the successful raid that killed terror mastermind Osama bin Laden, but it is important that the countries find a way to mend their frayed relationship in the wake of the attack, U.S. Sen. John Kerry said Monday during a visit to Islamabad.

Kerry said his goal in visiting was to begin a process that would leave the United States and Pakistan in a position where "isolated episodes, no matter how profound, do not jeopardize the relationships between our countries."

But he said Pakistan must choose between being a haven for extremists or a tolerant democracy and that the United States is willing to help the country.

"Our progress in the days ahead will be measured by actions, not words," he said.

Although many in Pakistan have accused the United States of violating Pakistani sovereignty by launching a unilateral military attack inside the country, Kerry said Pakistanis should direct their ire at bin Laden and his legion of foreign fighters, who he said were responsible for thousands of deaths inside Pakistan.

The Pakistani parliament recently condemned the raid, adopting a resolution calling for a review of its counter-terrorism cooperation agreement with the United States. The resolution also ordered the immediate end of drone attacks in a tribal region of Pakistan near the Afghan border.

Failure to end unilateral U.S. raids and drone attacks will force Pakistan "to consider taking necessary steps, including withdrawal of (a) transit facility" that NATO uses to send troops and supplies into Afghanistan, the resolution said.

U.S. officials have questioned how the world's most wanted terrorist managed to live in plain sight for years in Pakistan - near the country's elite military academy - without being detected.
