Pakistan and Afghanistan share same culture, religion and history, but the main issue of fight between them is Durand Line. The rise in the terrorist attacks has destroyed friendly relations between them. After the Cold war, Afghanistan became a serious threat to Pakistan and when the USA attacked Afghanistan for swiping away the Taliban regime, this threat increased many times. After the incident of 9/11, the NATO forces forced Pakistan to become their ally in the War. Federally Administered Tribal Areas (FATA) became home of militants because of the low security of the Pak - Afghan border which resulted in increased militancy in Khyber Pakhtunkhawa (KP).The increase in the terrorist attacks in the region has not only raised the death ratio but also damaged the infrastructure and economy of FATA and KP particularly. At the end of 2014, the withdrawal of U.S. troops from Afghanistan did not completely suppress Afghanistan's Taliban. It also encouraged Pakistan Taliban to control the Pakistan government in the same way. Pakistan should establish a friendly relationship with Afghanistan. This is not only conducive to the stability of the internal situation in Pakistan, but also to the improvement of bilateral relations with India. As a result, it will be easy to visit the Central Asian republic, and China will be more conducive to Pakistan in this respect.
