Ramaswami: Diasporic Hindus are the Prime Minister’s biggest cheerleaders as well as generous donors for his party, the BJP. Consequently, Modi batted no eyelid before bringing them all “home” in specially-organised air planes as the Covid-19 epidemic started scaling up in different countries. Fair enough. But what happened after they returned? Were they tested? Were they isolated? Were they quarantined when necessary? If ‘yes’ is the answer, then we would not have to shudder at the thought of the impending doom that community transmission of the virus means for the 1.3 billion Indians today.
