This paper analyses the management of foreign languages in the language planning of Afghanistan after the fall of Taliban. The analyses assess the suitability of foreign languages performing developmental and peace-making roles in domains where distribution of power is contested by the Afghan ethnolinguistic groups. Primary data of the paper comes from a questionnaire based survey and followup interviews. Analysis reveals the presence of various modern languages such as French, German, Russian and English in Afghanistan. The acceptance of foreign languages especially English is overwhelming in Afghanistan. Among foreign languages, English happens to be the most vigorous and promising language. However, a significant portion of Afghans oppose the growing influence and power for the foreign languages in Afghanistan. The paper notes, an uneven spread of English as the dominant foreign language in Afghanistan. Therefore, foreign languages' role in development and peacemaking may not be achieved due to lack of equal access. The paper recommends a wide-range of interventions to help in making foreign languages a resource for development and peacemaking. The intervention includes social, economic and political equality and equal opportunities in learning of foreign languages. It is also emphasised that the promotion of local languages is not to be affected by the availability of foreign languages.
