The reason why a large number of Afghan refugees poured into Pakistan and other neighboring countries in 2002.

To put it simply, northwestern Pakistan was once a part of Afghan territory, mainly inhabited by Pashtuns. Pakistan was a British colony before the independence of 1947 (Pakistan is a part of India, namely Britain (India)). /kloc-In the 8th century, in order to prevent the Soviet Union from going south and turning Afghanistan into a buffer zone between Britain and the Soviet Union, Britain kept a line-Duran Line on the northwest border of Pakistan as the boundary line between Britain and the Afghan government. However, successive governments in Afghanistan have refused to admit it, which is why there is a problem of "Pushtun Nistan". In other words, an artificial border divides a nation into two countries. They live in the same clan, or linked by tribal ties, or related by blood, and have frequent contacts. Therefore, after the outbreak of the war in Afghanistan, the first choice for Afghan refugees to flee is naturally Pakistan, which is inextricably linked with it. Secondly, the Pakistani government's refugee policy is comparable to that of other countries.
