The United States wants to make sure Afghanistan does not become a safe haven for Al Qaeda and does not destabilise its neighbour Pakistan, US President Barack Obama said. In an interview with NBC News, he said his administration would have clear objectives in Afghanistan and wanted to fix the drift that occurred there over the last two years. "We are not going to be able to rebuild Afghanistan into a Jeffersonian democracy," Obama said. "What we can do is make sure that Afghanistan is not a safe haven for Al Qaeda. What we can do is make sure that it is not destabilising neighbouring Pakistan," he told NBC. Obama also said he feared the detainees freed from Guantanamo would resume attacks on the United States.
