For what? He only partially translated the text. Pannun literally issues a threat in the video: "Jaanu khatra ho sagda hai" which translates to "Your life will be in Danger". He is telling the Sikhs not to board Air India flights after November 19th and that there will be threat to their lives. In other words, he is saying they will repeat what they did to Air India Flight 182: bomb the planes mid air. And that Sikhs should not travel Air India from November 19th onwards as he doesn't want any Sikh to lose his/her life in the bombings.
Just ask any Punjabi speaker and he will tell you the same thing!
I can't believe you people see conspiracy in everything! Get your head out of the sand. The West is harbouring dangerous criminals and terrorists. They owe you no loyalty. They will destroy your society. India is in the right here.
