I think its not only pakistani but even muslims have not understood the purpose of creation of pakistan and as a result they have not been able to explain it.
The purpose of paksiatn was not to create division between hindus and muslims or muslim and kaafir. It was to do what the prophet of islam did in case of madinah state and long before him Moses did for children of israel and much earlier Abraham did and long before him noah did.
The quran is all about humanity as a whole doing well. However it is not possible to make everyone everywhere do well at the very same time.
Each prophet tried to make his people see sense but when they failed he took those of his people who heeded him and moved away to create a place as an example to show to the rest people how to live a good life. It is clear from the quran that how those set new nations progressed and prospered till they stopped living according to divine program and so the whole thing was repeated all over again and again.
Sir seyyid ahemd khan, iqbal, jinnah and others before them and after them understood this very clearly but they always were in a minority. Most people believed in supernatural in wrong sense and were superstitious people. They were not educated much nor were they logical and realistic. Also there were always enemies from within and outside that opposed islamic outlook on life. They created trouble. The same happened when idea of pakistan was conceived. People just did not bother to know what the idea behind creation of pakistan really was.
When people are locked in any struggle things just take their own direction beyond the control of anyone. Originally all were happy to struggle for independence of india but then differences began to emerge because of various parties. Muslims are not forbidden to live with anyone so long as they have freedom, justice, fairness, compassion , brotherhood, progress and prosperity. The rest are muslims' personal beliefs and laws. Likewise muslims are not stopped from living with nonmuslims in an islamic state on same basis. All people are allowed freedom for their personal religious beliefs and laws.
So where is the problem? The problem is with people who like to be in positions of power to use and abuse other people at will. Such people are everywhere claiming to be hindus, jews, christians, muslims and even secularists and atheists.
Such people of such mindset and attitude cannot hide themselves if one really tried to know them.
Many people write books to make money and fool others, only people who love humanity and live for others care for others and it is those who need to be listened to.
Jihad is not about killing hindus and jews, it is about fighting against those who take away freedom of people, who practice injustice and unfairness and show cruelty and animosity toward mankind. Who force poverty and ignorance upon mankind.
As far as islam is concerned, people are free to believe what they like and do what they like but islam does not allow people to inflict damage on humanity or to destroy it.
As for nonmuslims, they can help muslims by helping them educate themselves and others. Islam is a very powerful idea and it is succeeding against all odds. All people need to wake up about islam because they will find it helpful.
I think all people should read the quran for themselves and see what it really says and not listen to any mad mullahs.
