It's jealousy Afghans have a hard-on for punjabis and always play the ethnic card.They are bitter about going from an empire who raided the sub-continent at will to the failed state they are today and also due to durand line. I have said the same thing a you for years. They voted against recognition of pakistan, our first assassinated leader was killed by an afghan and they tried to invade bajaur and launched scud missiles at us in the past- all this was way before taliban even the burqas, gun and drug culture was introduced by them.
They become even worse and really been in the stone age since the soviet invasion though. They have not achieved anything as a nation anything except tribalism,bacha bazi and producing opium we are lucky to not be from that cursed place. All they can do is attack schools,mosques and hospitals like cowards but IA we will bring them to justice.
