Pakistan is facing existential threat from the western border;Afganistan is an evil state ,and it will try to impose war on us in future ,once it gets stable & powerful .They have not been able to cross this border for last 200 years ,and now they are eager to cause loot & plunder in this part of the world again.Afgans are our natural enemies for centuries ,while India is an artificial enemy,being created after 1947.PA is doing a great job of securing this western front and preparing itself to face possible aggression from savage Afgans.
