I think its a very good decision because Pakistan has solid proofs that India is already destabilizing Balochistan and Tribal areas through Afghanistan and investing heavy funds in Afghanistan for its own benefit. Hamid Karzai is a pro Indian and against Pakistan who spent many years of his life in India. Even the name of new Afghan Intelligence is Rama that is an Indian word.
India is increasing its presence in Afghanistan to destabilize the Pakistan so its a very good decision by Pakistan to not allowing Indian trucks to move through Pakistan to Afghanistan.
