After 1984 golden temple and Delhi riots, everyone in the Pun jab wanted to separate from India and there was strong freedom movement going on but by 1992 Indian government killed all those khalistan supporters and whoever left had to go to Pakistan, Canada, UK or Europe.
some conspiracy theories are that Punjab congress govt. of 1990s made fake khalistan groups and those killed or looted own punjabi people and thats why khalistan movement ended.
But time has changed and despite of that fact most people want separate nation as khalistan but no body wanted to kill anybody for khalistan but now govt is providing all resourses to punjab and trying to heal the wounds of 84.
Nobody talks abt khalistan these days in punjab as people are more busy in jobs , agriculture and most of young guys are more concerned abt careers, education, movies and girls.
