That my friend is contingent on the degree to which we'd be willing to embrace the other as our own & to rise above (not forget) our ethnic & linguistic differences.
I'll answer it thus : The Kalash dance, though alien to the rest of Pakistan, is seen as a part of 'Our Culture/Traditions'...why ? We're not from those lands & that dance certainly isn't an off shoot of either the Khattak dance or the Bhangra & yet we're willing to own up to it as our own - Why ?
Answer : Because they're Pakistanis ! And despite our differences...that means a lot to the vast majority of us. We mustn't underestimate the bond of 'localized Pan-Islamism' that this country was founded upon. There is a reason why you'd see millions of Baloch in Sindh, Punjab & KPK, millions of Pashtuns all over the country & millions of Punjabis everywhere living in what were traditionally thought of as each other's ancestral lands; And the reason being - We're comfortable with each other...we're very comfortable with each other ! That thing about Islam bringing us together isn't just fluff. The reason why I as a Punjabi-Kashmiri would be able to appreciate the Pashtunwali is not because of something that was refined at the time of Ahmed Shah Abdali but because it in some ways shares some of the values I share; values we derived from Islam & incorporated in our own cultures.
