You can 'demand' but without internal stability & unity no one will take your 'demand' seriously. Unfortunately the current state Pakistan finds itself in.
I cant speak for Cheng, but when even the citizens of Pakistan are not united and don't respect the institutions, expecting that same respect from foreigners is wrong.
In other words, you need not even demand anything. Just develop your nation internally and the respect will automatically come without you even demanding it.
Pakistan is as united or divided as any other country in the World. Its just that many other countries do not have as many external factors to cater to as Pakistan does.
What most Pakistanis agree upon is that Pakistan cannot be made into the sacrificial lamb and give up all her regional interests just because the Americans decide otherwise. There is consensus on that and the future Pakistani stance would be much more mindful of the feelings that people have and the government will use this perception amongst its constituency to frame future policies.
