WASHINGTON (Agencies) - Backing the 'hot pursuit' of Al-Qaeda targets inside Pakistan, Afghan President Hamid Karzai has said he would fully support an American attack at suspected Al-Qaeda and Taliban hideouts in the neighbouring country that is based on actionable intelligence. Karzai, however, said any decision to let US troops cross Afghanistan's border should be taken collectively by Pakistan, Afghanistan and the United States. "I would fully back President (Barack) Obama in attacking Al-Qaeda wherever they're found. If they're found in Afghanistan, I would fully back him in doing that. If they're found in Pakistan, I would fully back him in that," Karzai said in an interview on CNN's "Fareed Zakaria GPS", scheduled to air Sunday. "On the question of crossing troops from Afghanistan into Pakistan in pursuit of Al-Qaeda personnel, or for destruction of Al-Qaeda hideouts, or training grounds, or sanctuaries, this is something that the govt of Afghanistan, and Pakistan, and the US must work together and agree upon together, and then implement," Karzai said in the interview. Obama had said during his campaign that if actionable intelligence was found he would attack Al-Qaeda hideouts in Pakistan, even without the approval of Islamabad. The Afghan President said with a resurgent Taliban, a still-flourishing drug trade and a border with Pakistan believed to be home base for Al Qaeda, Afghanistan cannot afford for US troops to leave any time soon. The task for US forces in Afghanistan "is not over", he added. "US forces will not be able to leave soon in Afghanistan because the task is not over," Karzai said. "We have to defeat terrorism. We'll have to enable Afghanistan to stand on its own feet. We'll have to enable Afghanistan to be able to defend itself and protect for its security ... ."Then, the United States can leave and, at that time, the Afghan people will give them plenty of flowers and gratitude and send them safely back home." At the same time, Karzai said, the actions of troops in Afghanistan have turned some of the public against them. "It's the question of civilian causalities. It's a question of risk of Afghans. It's the question of home searches," he said. "These activities are seriously undermining the confidence of the Afghan people in the joint struggle we have against terrorism and undermining their hopeful future. "We'll continue to be a friend. We'll continue to be an ally. But Afghanistan deserves respect and a better treatment." While he said he welcomes additional US troops, Karzai suggested they need to work along the Afghan-Pakistan border and in the poppy fields that fuel a drug trade that threatens to turn the nation into a narco-state - not in the villages where most Afghans live. "We have travelled many years on. What should have happened early on didn't, unfortunately, happen," Karzai said. "Now, the country is not in the same mood as it was in 2002. And so any addition of troops must have a purposeful objective that the Afghan people would agree with." Speaking via satellite from Kabul, Karzai called former president George Bush "a great person", but said he can work with Obama despite the President's comments as a candidate that Karzai had "not gotten out of the bunker" to improve security and infrastructure in Afghanistan. "President Obama is a great inspiration to the world," he said. "The people of America have proven that they can really be the light holders for change and the will of the people in the world. "And his coming to power by the vote of the American people is a manifestation of that great power of the American people." Karzai also acknowledged corruption in the Afghan government, but defended the work he's done to combat it. "Sure, corruption in the Afghan government is as much there as in any other Third World country," he said. He said a government department has been created to deal with corruption and that corrupt judges, administrators and other officials are dismissed "daily" over corruption charges.
