AC360 Preview: Diplomat defends Pakistan's commitment to fighting terrorism

Editor's note: Tonight on AC360°, Anderson Cooper speaks with Husain Haqqani, Pakistan's ambassador to the U.S.

(CNN) - With each passing day, new revelations about Osama bin Laden’s presence in Pakistan for years before his recent death are placing strains on the vital relationship between Pakistan and the United States.

The Pakistanis are fending off accusations that they were essentially sleeping on the job or, worse, may have been complicit in hiding the world’s most wanted terrorist. At the same time, they have accused the U.S. of violating their national sovereignty with a secret military operation in the country that hunted down bin Laden.

It hasn’t helped that Pakistani officials have been sending mixed messages on several critical issues: whether there will be a full inquiry into who knew what about bin Laden’s half decade in Pakistan, whether the U.S. can question bin Laden’s wives who are now in Pakistani custody, and whether the Pakistanis will allow China to examine the wreckage of a previously undisclosed American stealth helicopter used in the mission that killed bin Laden.

Many Americans now have their doubts about whether Pakistan can be a trusted partner in the war on terror. Husain Haqqani, Pakistan’s Ambassador to the U.S., insists that his government has been holding up its end of the bargain.

Watch Haqqani’s interview with Anderson Cooper tonight on AC360° beginning at 10 pm ET and judge for yourself whether you believe him.
