Narendra Modi’s government is trying to silence US critics of its authoritarian turn — and it’s succeeding.

India’s efforts include a handful of high-profile incidents, most notably an assassination plot against American and Canadian activists. But more commonly, India engages in subtle forms of harassment that fly under the public radar.

An American charity leader who spoke out on Indian human rights violations saw his Indian employees arrested en masse. An American journalist who worked on a documentary about India was put on a travel blacklist and deported. An American historian who studies 17th-century India received so many death threats that she could no longer speak without security. Even a member of Congress — and vocal critic of the Modi regime — said she was concerned about being banned from visiting her Indian parents.

“I’m always thinking about the impact on my family — for example, if there was some attempt to not allow me back into India,” says Rep. Pramila Jayapal (D-WA).

In some ways, the Indian campaign is more brazen than Russia’s meddling in the 2016 election. While no evidence has emerged that Russia threatened harm against American citizens and their family members, India has been caught doing so repeatedly.
