1. This op shows how ruthless India can be to protect the Brahminic hegemony over the throne of Delhi. Indira had created Bhindranwelle for political gain in Punjab, but this backfired terribly. The sword arm of India, the Khalsa, will never be a sword again. A free Khalistanis a matter of time. During the hay days of Khalistan insurgency E Punjab had become a buffer between India and Pakistan. We will see that again eventually.
2. Udham Singh had waited 19 years to take revenge. Sikhs have produced the likes of Kartar Singh and Bhagat Singh. This is a nation which sacrificed lives again and again for honor and freedom. Remember how Indira was gunned down? A Sikh youth was caught by security agencies hiding for about a week without food and water inside a bush near the Indira samadhi. He had a revolver with which he planned to kill Rajiv who was due to offer his respects at the samadhi. The Sikh boy was totally disheveled and suffering from malnutrition and dehydration. The security detail had come to scan the area. This is the nation the Brahminic oligarchy has upset. Or recollect Sukhdev Singh Sukha and Harjinder Singh Jinda who killed Gen Vaidya in Pune.
3. It was a totally stupid action which Gen Sinha had refused to undertake. Vaidya and Sundarji were rewarded for their compliance with Indira. IA used tanks and field guns firing HE and Smoke. This was a totally brute action where other methods could have worked. Perhaps it was Indira's ego at what she felt was Bhidranwalle's betrayal. (Her son was similarly killed by LTTE created by India; jaisa karo'ge oisa bharo'ge.)
4. A lot of Sikh youth were shot dead in cold blood at the temple after the op was over. 10 Guards, the point Bn who had suffered high casualty might have done this. The paratroopers were also involved in cold blooded killings. It is said Bhindranwalle and Gen Sabegh Singh were discovered alive in dazed state in a basement. They were killed promptly.Smoke and incessant tear gas shells had taken their toll. The Gen had recently suffered a heart attack. The families never saw an autopsy report because none was done to hush up the misdeed.
5. Btw, there were some BD youth trapped in the basement. These people used (and still do) the hospitality the gurdowaras in their travel to/from Pakistan without travel docus.
