( CNN ) -- Pakistan has been an unreliable ally of the United States in the war against al Qaeda and other extremist organizations , U.S. Vice President Joe Biden told CNN in an interview set to air in full Monday night . Biden , who spoke to CNN 's John King on the eve of the 10th anniversary of the 9/11 terror attacks , said Pakistan has failed `` on occasion '' when forced to choose between the United States and al Qaeda . The price of Pakistan 's choices has been the `` loss of life of American soldiers in Afghanistan , '' the vice president said . Islamabad has `` been very helpful in other times , '' he added . `` But it 's not sufficient . They have to get better . We need a relationship that is born out of mutual interest . And it 's in their interest that they be more cooperative with us . '' `` We are demanding it , '' he said . Al Qaeda leader Osama bin Laden was killed by U.S. forces in a compound in Abbottabad , Pakistan , in May . Pakistan 's government -- which has struggled with significant pro-al Qaeda sentiment within its borders -- was not informed of the attack beforehand . Pakistani authorities insist they did not know bin Laden 's location . Despite troubles in Pakistan and elsewhere , the United States is `` getting close '' to bringing about an end to organized , legitimized terrorist activities , Biden said . `` We have done great damage to ... al Qaeda , '' he said . `` Satellite organizations '' have emerged in Somalia and elsewhere , he said , but `` they are less coordinated '' and `` less capable . '' `` And we 're relentless in pursuing them , '' he added . As a result , Americans are safer today than they were a decade ago , Biden asserted . Regardless , the vice president cautioned that `` there is always a possibility of a lone wolf '' attack within the United States or elsewhere . `` There 's always a possibility of an incident occurring , but I do not believe there 's anyone right now capable of putting together the kind of extremely complicated planned operation that took place on 9/11 , '' he said . Biden said he believes that in 25 years , Americans will `` read about this period of terror as ... a part of a chapter in the history of this country . '' The vice president denied former Vice President Dick Cheney 's assertion that controversial interrogation techniques such as waterboarding -- stopped by the Obama administration -- would help generate useful intelligence in the war against al Qaeda and other organizations . `` I 've seen zero evidence that it works , and I think there 's abundant evidence that it hurts us internationally . It hurts our security , '' Biden said . It does so , he said , `` by making a mockery of who we say we are and giving rationale for those who want to do us harm to recruit people . ''
