If the state of Pakistan did not Allie itself with the United States of America this internal semi civil war would not have occurred. Not only this, if you fund my neighbor to bomb my house id probably bomb you as well. ...get my drift?
And Pakistan would have been declared a terrorist state by the world community which would have led to a total collapse of Pakistan with trade and economic sanctions imposed on Pakistan
Pakistan would resemble Somalia today.
Pakistan does not have Oil like Iran to survive being labeled a terrorist state.
