No Afghan government, not even the Taliban regime, has ever accepted the Durand Line as the international border with Pakistan; nor would any Afghan leader ever consider such a step. For the Afghans, especially the Pashtuns, the country’s leading ethnic group, it is a symbol of a historic injustice deceitfully forced upon them by the British. For Pakistan, which considers itself as a successor state, to persuade the Afghans to make it the formal border has always been a top foreign policy priority.
