Can someone here tell me at least 5 things which distinguishes Pakistan from north India?
I feel if I visit Indian Punjab or jammu or haryana, I need not visit Pakistan... Instead it is worthwhile visiting eastern India or southern India as they are linguistically and culturally much different than north.
I have not been to Indian Punjab but I have had the opportunity of visiting Northern Indian cities of Panipat, Delhi & Agra as well as Madras /Chennai & Bombay /Mumbai of Southern India. I have also travelled widely across Pakistan.
I did not notice a significant difference between the food & culture of Panipat, Delhi & Agra and that of Lahore. It could be that so many migrants from Pakistani Punjab moved to Delhi and also many Indian Muslims from Haryana, Punjab & UP came to live in Lahore. However, Lahore is only one city of the Pakistani Punjab.
I would concede that language, food & culture of Lahore, Gujranwala, Sheikupura, Sialkot, Gujarat and Okara
and that of Amritsar, Pathankot, Gurdaspur, Ludhiana etc and of the population of Haryana, Uttar Pradesh & Delhi that speaks the standard Punjabi language (language of the Punjabi movies) is quite similar
Travelling west towards the districts of Sargodha, Khushab; one comes across Watwatti/Shahpuri dialect speakers which is distinct from the Majha language of Lahore.
Travelling North towards Jhelum, Gujjar Khan & Rawalpindi we meet Potohari speakers. Here you also notice the difference in the dress & culture in general.
Further north along the Indus you will find Hindko speakers where culture and the food are similar to the Pashtuns but the language spoken is easily closer to Punjabi.
Travelling south, once you cross the Sutlej and enter the Saraiki belt, you find a different culture and the food tastes slightly different. Saraiki belt includes Riasiti (dialect of Bahawalpur & Cholistan). Multani & Thali varieties of Saraiki are spoken in the region around Multan & towards the west around DG Khan.
The above was only about Punjab. Pakistan has three more provinces & the Northern areas.
Sind is an ancient land with her distinct dress, food, language & cultural heritage going back to the Mahabharata times. Sindhi Biryani and fish taste like heaven.
KPK with the Pashto & Hindko language speakers again has a rich literature, different dress & food. No bread tastes better than the Nan available at the KPK tandurs and their Chapli kebabs are worth dying for.
Baluchistan is a world on its own and includes the Brohi speakers; a language of the Dravidian family. There are places where I had to resort to the sign language to make myself understood. In Quetta, one comes across Persian/Hazargi speakers of the Hazara tribe who claim to be pure blooded Mongols. Here you have the delicious 'Sajji' a food unique to the Baluchis.
In the Northern areas, you meet Chitralis where some clans claim to be decedents of the Greek army of Alexander.
It is your privilege to decide whether to visit Pakistan or not. But Pakistan is not an extension of Northern India and any visitor will notice at least as much difference, if not more; between Delhi & Peshawar and between Delhi & Quetta as he would between Delhi & Cochin.
