Operation Blue Star and its violent aftermaths popularized the demand for Khalistan among many Sikhs dispersed globally. Involvement of sections of Sikh diaspora turned out to be important for the movement as it provided the diplomatic and financial support. It also enabled Pakistan to become involved in the fueling of the movement. Sikhs in UK, Canada and USA arranged for cadres to travel to Pakistan for military and financial assistance. Some Sikh groups abroad even declared themselves as the Khalistani government in exile.
