Every time the current leadership in Kabul and its population attempt to talk about taking sovereign land from Pakistan, then retribution will most certainly be on its way and they will know true despair. If the national interests of Pakistan dictates the assumption that we must support the Afghan Taliban to secure our borders, then the fate of Afghanistan is the least of our concerns on who actually controls the country as long as they pro-Pakistan.
Pakistan also has concerns because Radio Mullah is hiding in their country, however you don't actually see the constant accusation and warmongering rhetoric in our media calling out for blood on the Afghans. Furthermore, they are an ungrateful bunch who we have fed and housed in our country for more than 30 years and they still have the audacity to talk negatively about Pakistan. Everyone in Pakistan understand's the involvement of the Indian intelligence in supporting the Baluchistan Liberation Army, therefore please save your preaching lessons to someone who actually gives a flying hoot.
