The countries involved in the NATO military mission in Afghanistan should provide a "fair share" of the funding for Afghan security forces after international combat troops pull out in 2014, the alliance's chief said Wednesday. Secretary General Anders Fogh Rasmussen told reporters in Brussels that "around 4 billion dollars" a year was needed for the purpose but "no final decision" has been made, DPA reported. "I would expect NATO allies and ISAF partners to commit themselves to pay a fair share of the total bill." "It is less expensive to finance Afghanistan security forces than to deploy foreign troops in Afghanistan," he added.
