NEW YORK - President Asif Ali Zardari has strongly denied Pakistan government's involvement in last week's attacks on Mumbai and said the gunmen were "stateless actors" who operate across the region. "The state of Pakistan is no way responsible," Zardari said in an interview with CNN's Larry King Live. The gunmen and the planners are holding the whole world hostage, he said. The president, who is in Islamabad, was interviewed via satellite. He was seated in the resplendent presidency with two flags-the green crescent-and-star and the president's standard-behind him, while and two presidential guards in red tunics looked on. Responding to a question, Zardari said his government has not been given any proof that the surviving attacker is a Pakistani. "We have not been given any tangible proof to say that he is definitely a Pakistani. I very much doubt ... that he's a Pakistani." "The gunmen, plus the planners, whoever they are-they are stateless actors who are holding hostage the whole world," he said. Questioned about the involvement of Lashkar-e-Taiba, he said the Pakistan government wouldn't know, as it is a "banned organization." "Again, they are people who operate outside the system. They operate like - al-Qaeda, for instance, is not state-oriented. They operate something on that mechanism, and ... I've already offered India full cooperation on this incident, and we intend to do that." "I'm firmly committed to fighting terrorism per se," he said. "That's why we are fighting them every day." Zardari said if India produced evidence that a Pakistani group was behind the attacks, his government would take action against them. After the attacks, India renewed a long-standing demand Islamabad hand over about 20 fugitives New Delhi believes are hiding in Pakistan. Zardari said if India provided proof against the fugitives, Pakistan would let its own judiciary handle the cases. "If we had the proof, we would try them in our courts, we would try them in our land and we would sentence them, he said. Denying any involvement of the Pakistan government, Zardari said, "Even the White House and the American CIA have said that today. The state of Pakistan is, of course, not involved. We are part of the victims, Larry. I'm a victim. The state of Pakistan is a victim. We are the victims of this war, and I am sorry for the Indians, and I feel sorry for them." The president said his elected government has nothing to do with any militant activity against India. "I can assure the world from my side, from my Army's side, from my parliament's side and the people of Pakistan that we are not helping any such activity." Zardari confirmed he is willing to have Pakistani security officials participate with India in a joint investigation. "We have offered to take this step forward and cooperate with the Indians. I am willing to have my security advisor and their security in charge of our intelligence security and their intelligence security, have a joint committee which we have proposed to the Indians for a joint investigation in the Mumbai incident." Questioned about the possibility of Indian military strikes against terrorist camps in Pakistan, Zardari said it would be counterproductive to collective efforts against terrorism in the region. "I would not agree with that because this is a time to come together and do a joint investigation and look at the problem in the larger context. We have a larger threat on our hands. "The threat is in the region, and just not to Mumbai or to India. The threat to the state of Pakistan. There's a threat to the state of Afghanistan. It's a threat throughout the region. So that would be counterproductive." Zardari said the whole nation of Pakistan is "united to ... becoming friends with India," he said, adding that he stands for working towards peace with its neighbour. "I am looking forward and I am hoping that I will be the catalyst that makes India and Pakistan live in peace forever.... I am looking forward to making it a regional economical zone. I am looking forward to working in all walks of life together and India is a neighbour, it is 1 billion plus people, it's a market, it's an opportunity, relations with India is an opportunity for Pakistan." Zardari said he stands for working towards peace with India. On whether the Mumbai attacks could trigger a fourth war between the two South Asian nuclear powers, Zardari said: "Democracies don't go to war. All those wars you're talking about did not take place in any democracy. They all happened in the times of dictators. ..." He said Pakistan looks forward to working with President-elect Barack Obama to advance Pakistan-US relations and find a regional solution to the challenges of violent extremism. "I'm hoping that the new administration coming in will work with us to look into it for a regional solution. We've been advocating a regional solution". "We need more participation from our neighbours, India, China, and extended neighbours as such in the UAE. We all need to come together on a collective mindset and find solutions to that problem." He said extremist violence is a problem his democratically elected government has inherited. "It's part of the Afghan problem, part of the war in Afghanistan, part of the war in our northern regions." Asked what he made of President-elect Obama, the president, in a reference to expectations around the world, said, "There is a world romance with Obama." "And we all in Pakistan - we are looking forward to working with him." Asked about former first lady Hillary Clinton's being Secretary of State in the Obama administration, the President described her an "excellent choice" and a "good friend of Pakistan." "I am looking forward to working with Hillary Clinton. We know each other, we've met before, we have known each other for a long time, since my wife's time. She has been a good friend of Pakistan in the past and we hope to work with her, we're looking forward to working with her."
