Sikhs don't have any world class leader because Sikhs don't have a leadership structure required for leaders to emerge and develop.
Sikhs are led by Witch Doctors who capture the minds of the Sikh community.
The Witch Doctors waste Sikh's money on spiritual entertainment (ਗੁਦਗੁਦੀ), moral self indulgence (ਮਨ ਦੀ ਸ਼ਾਂਤੀ), and catharsis (ਭੜਾਸ).
Sikhs don't fund their best to rise to global level as world leaders and statesmen.
Sikhs don't have a leader becasue they spend money on converting dalits to Sikhs, rather than developing Sikhs to be world class leaders.
Sikhs will sponsor morcha and protest against Indian State. But they will never sponsor Sikhs to attend conferences to engage with decision makers.
Sikhs dont have a leader because they never did anything to develop world class leaders.
Will world class leaders automatically drop out of sky into our lap by magic without putting in the effort to develop wolrd class leaders?
The way out is to support the wisest and most capable Sikhs so they can analyze and solve the problems rather than entertain you with empty promises, false hope, and empty emotionalism.
