NEW YORK (AFP) - The UN envoy, who helped set up Afghanistan's post-Taliban government, has warned the country is unravelling, saying an upcoming US-backed conference must undo years of neglect. Lakhdar Brahimi, a veteran UN diplomat from Algeria, chaired the 2001 Bonn conference that established President Hamid Karzai's administration after a US-led offensive threw out the Taliban regime. "We are now paying the price for what we did wrong from day one," Brahimi said in an interview with The Nation magazine in its latest issue. Asked what has unravelled since Bonn, Brahimi said: "I'm afraid, almost everything." Brahimi said a new Afghan conference - slated for March 31 in The Hague after it was proposed by US Secretary of State Hillary Clinton - "comes after six very long, wasted years." He said he pleaded for a new Bonn conference in 2003 but "nobody was listening" as then US president George W Bush focused attention on invading Iraq. Brahimi said that Karzai's base was too narrow to begin with and that the international community in recent years had no common strategy other than waging a vague "war on terror." Brahimi noted that the Taliban never surrendered, with most members simply reintegrating into the countryside or going to neighbouring Pakistan. "To be sure, the Taliban are not universally liked in Afghanistan," Brahimi said. "I am afraid today's government is not much better than that of the Mujahideen after the withdrawal of the Soviet Union." "We now have a very, very serious situation," he said. Meanwhile, the European Union has ruled out sending more troops to Afghanistan but is willing to do more to help stabilise the country in other ways, the bloc's foreign police chief Javier Solana said Tuesday. "EU countries in principle do not think they will increase the number of their troops which they want to deploy in Afghanistan," the former Spanish foreign minister told public radio RNE. "The situation in Afghanistan is not going to be resolved only militarily. There are many things that can be done in Afghanistan that are not exclusively increasing the number of troops," he added. Meanwhile, cutting a deal with "moderate" Taliban may be gaining favour among Western leaders, but it could be a long way off given the growing strength of the Taliban and the weak Kabul government, experts say. While (Obama's) approach offers a potential way out of a long, bloody war in Afghanistan, where more US troops are headed, conditions there are much different than Iraq and seem to work against any imminent talks with "reconcilables" in the Taliban, analysts said. "I think it's one aspect of the strategy they want to pursue but it is fraught with difficulties," said Simon Henderson, a senior fellow at the Washington Institute for Near East Policy. Even if a successful deal could be struck with Taliban, the real power lies with the hardline leadership of the group that allegedly operates from bases in Pakistan, out of the reach of US and Nato ground forces, experts said.
