NATO's secretary general Anders Fogh Rasmussen has argued against a retreat from Afghanistan saying the duration of the international troop presence would be 'driven not by the calendar but by commitment. His comments came a day after an international conference in Kabul decided to hand over security to Afghan forces by 2014. Mr. Rasmussen today met Pakistan Foreign Minister Shah Mehmood Qureshi in Islamabad to discuss the Afghan situation. He said the troop presence would be determined by the security situation and that NATO will not leave Afghanistan prematurely. Mr. Rasmussen expressed fears that the Taliban could take over the country in case of hasty pullout, and pose a great risk to the international security.More than 140,000 international troops from the US and NATO are in Afghanistan and domestic pressure is mounting on individual nations to bring the soldiers back. Pakistani Foreign Minister Shah Mehmood Qureshi said the country sought no role for itself in Afghanistan but would help to create peace if asked by the Afghans to do so.
