Indira Gandhi killed millions of Sikhs? While thousands of innocent Sikhs died in Operation Bluestar, they were caught in the crossfire with Khalistanis who were holding hostages. Do you know how many zeroes there are in a million?

As for her bodyguards, her security advisors told her to remove the Sikhs. She didn't think that Sikhs hated her. After all, she is the one who created the Sikh majority state of Punjab. Prior to that, it was a Hindu state (Punjab and Haryana were one state).
