US Secretary of State John Kerry has urged Afghanistan's Taliban militants to follow the recent example of a notorious warlord and make an honourable peace with the Kabul government. <br/><br/>Mr. Kerry told an international donor conference in Brussels today. He said that there is a path toward an honourable end to the conflict that the Taliban have waged, it is a conflict that cannot be won in the battlefield. <br/><br/>US Secretary of State said a peace deal signed last month by Gulbuddin Hekmatyar, who heads the Hezb-i-Islami group and was a key figure in Afghanistan's civil war in the 1990s, was a model for what might be possible.<br/><br/>He said that a peace deal would in fact achieve the Taliban's aim of expelling foreign forces from Afghanistan, 15 years after a US-led invasion drove the Islamist group from power. <br/><br/>Mr Kerry said a political settlement negotiated with the Afghan government is the only way to end the fighting, ensure lasting stability, and achieve a full drawdown of international military forces, which is their goal. <br/><br/>He added their goal of ridding Afghanistan of external forces will not come by the continued insurgency, it will come by peace.
