Accountability is extremely difficult to impossible where 1) army still makes the key decisions over riding civilian government 2) Pakistanis as nation are disintegrated on key issues. Indians are more fragmented, polarized and hate each other more than Pakistanis do but when national issues are at stake, they become cohesive one nation and act above ethnicity, culture and religion.
It is an unfortunate fact that army and b-team of army JI and its cronies has made foundation of Pakistan brittle. It can collapse at any time, unless army really works under civilian government and be responsible for their actions.
