AFGHAN President Hamid Karzai has said his government and Nato have failed to provide Afghans with security, 10 years after Taliban were overthrown. Speaking to the BBC, Karzai also accused Pakistan of supporting the insurgency, saying sanctuaries there still needed to be tackled. He vowed to step down in 2014 and said he was working on the succession. Karzai also traced some of Afghanistans current insecurity to military strategy in the early years of the war and the failure to tackle the Taliban allegedly sheltering in Pakistani tribal areas. Although he was eager to emphasise achievements in education and health, President Karzai admitted that security was his greatest failing. Weve done terribly badly in providing security to the Afghan people and this is the greatest shortcoming of our government and of our international partners, he said. On the overall policy of Pakistan toward Afghanistan and towards the Taliban, definitely, the Taliban will not be able to move a finger without Pakistani support, he said. Karzai told the BBC he believed the militant group was entirely controlled by Pakistan. He added that the president and prime minister of Pakistan were eager for good relations with Afghanistan but re-emphasised that Taliban sanctuaries in Pakistan will not go away unless the government there co-operates with the Afghan administration. President Karzai also admitted that the policy of talking to the Taliban had received a serious blow with the assassination of ex-president Rabbani but added: Find an address, find a location, and we will talk to you. He said he would return to talks, if he could meet people who clearly identified themselves as Taliban delegates. We have not said that we will not talk to them. We have said we dont know who to talk to, we dont have an address. The moment we get an address for the Taliban, (is) the moment we will talk to them. Karzai also confirmed that he would step down from the presidency in that year but added that he was starting work to find a successor. I feel it is my responsibility to be working on a next president that the Afghans can trust and that they can have faith in, and that he as the president can serve this nation, he said. The president also maintains that the corruption, which has marked his administration, will get better after 2014 when foreign forces withdraw. He blames such corruption on foreign companies and governments. The reality of the matter is that a very, very big part of big corruption in Afghanistan emanates from the international community, he said. Despite the advances in health and education, rights groups and aid organisations say many challenges remain. Correspondents say that Western officials admit that parts of the country will remain violent after 2014 when Nato stops fighting. Without a peace deal with the Taliban, he says, few really expect the war to be brought to an end. '
