NATO Secretary General Jens Stoltenberg on February 15 reiterated that the presence of the alliance’s troops in Afghanistan is "conditions-based", reports Tolo News. “Our common goal is clear. Afghanistan should never again serve as a haven for terrorists to attack our homelands. So, our presence is conditions-based,” Stoltenberg said. While no ally wants to stay in Afghanistan longer than necessary, we will not leave before the time is right.”
