Yes. https://en.wikipedia.org/wiki/Khalistan_movement is not a significant movement in India. I have plenty of connections with Sikhs and Sikhism in India. Apart from a very tiny minority of people, who quickly set off to Canada, this movement does not exist in India. They are courted by Canadian parliamentarians, which included Trudeau.
If it's such an insignificant movement, it's curious why India saw fit to assassinate a Canadian on Canadian soil. A claim that as near as I can tell only India and its surrogates (such as yourself, it seems) dispute.
Also, the veracity of a claim does not depend on who is making it or who is disputing it. The accusing investigation agency has do a proper investigation and submit proofs and ask for extradition.
Yes, Canadian investigators should have gone to India to investigate and build a case against the Indian government. That would have worked well.
Several countries examined Canada's evidence and found it satisfactory. Your government conducted an extra judicial execution of a Canadian citizen on Canadian territory. You are the baddies, even if your government assures you of the opposite.
You are resistant to all the actual information I have provided you. Your terrorists are killing more of your own citizens. But, I suppose Indian government should straightaway accept guilt for all such murders including that of Harjeet Singh Dhadda and an upstanding citizen Harpreet Singh Uppal. Mark Carney is cosying up to the same Indian government. I wonder which strategy of Carney will work on you: supply kool-aid or pretend there was never any problem. I'm betting on the latter.
