TTP is not fighting against an illegal occupation force. India is doing something illegal, Pakistan is the legal authority over its regions.
Kashmir being a disputed territory, it becomes our right to fight Indian soldiers there. There is no question of targeting anyone but the soldiers since we are fighting to save ALL civilians from India's tyranny.
Best thing is, India has the option to end the fight by accepting a peaceful, democratic way - plebiscite.
Either one thing has to happen, peace or fight. India's choice.
