We share common culture, we been movin in and out in each other's provinces for centuries..doing businesses...trading inter mingling in form of settlements....intermarriages, blood relationds....everyting from dress to food...etc.. And this has been going on for centuries...so our ancestors made it one country...We Pakistanies are proud of this union.
Your personal opinion cannot break Pakistan.....or change the course of history.
Thanks.
