🧠 Explanation:
Afghanistan opposed Pakistan’s United Nations membership in 1947 due to disputes over the Durand Line, a colonial-era border dividing Pashtun territories. Afghanistan’s rejection stemmed from claims that the line was invalid, fueling territorial tensions. This opposition marked an early strain in Afghan-Pakistan relations, influencing regional geopolitics. The Durand Line remains a contentious issue, studied in international relations and South Asian history for its impact on border disputes, national identity, and diplomatic challenges in the post-colonial era.
