This celebration of Trump in New Delhi in May, and others like it in India this year, are the work of a small, devoted and increasingly visible faction of Hindu nationalists in India and the United States who see Trump as the embodiment of the cocksure, politically incorrect, strongman brand of politics they admire.

That some of Trump’s most passionate followers are Indian may seem, at first, somewhat strange, given how fond he is of scorning Asian countries where cheap labour saps demand for American workers. A poll on Asian-Americans’ political leanings conducted in August and September found that just 7% of Indian-Americans said they would vote for Trump.

But in one of the more peculiar pairings of this most peculiar political season, Trump has unwittingly fashioned a niche constituency in the overlap between the Indian right and the American right, which share a lot of the same anxieties about terrorism, immigration and the loss of prestige that they believe their leaders have been too slow to reverse.

“There’s a lot of parallels there,” said Shalabh Kumar, founding chairman of the Republican Hindu Coalition. “Mr Trump is all about development, development, development; prosperity, prosperity, prosperity; tremendous job growth. And at the same time, he recognises the need to control the borders.”

As one of Trump’s biggest Hindu financial backers, Kumar, who runs an electronics manufacturing company in Illinois and grew up in Punjab, helped organise a speech by the Republican nominee in Edison, New Jersey, at a Bollywood-themed charity concert last Saturday.  The proceeds will benefit terrorism victims. “It will be an incredible evening,” Trump had said in a video promoting it, one of the few ethnic events he has agreed to do during this campaign.

Trump may be largely indifferent to the reasons behind his Hindu loyalists’ fervour, but his most senior advisers are not. The campaign’s chief executive, Stephen K Bannon, is a student of nationalist movements. Bannon is close to Nigel Farage, a central figure in Britain’s movement to leave the European Union, and he is an admirer of India’s Prime Minister, Narendra Modi, a Hindu nationalist Bannon has called “the Reagan of India.”

It may be pure coincidence that some of Trump’s words channel the nationalistic and, some argue, anti-Muslim sentiments that Modi stoked as he rose to power. But it is certainly not coincidental that many of Trump’s biggest Hindu supporters are also some of Modi’s most ardent backers.

At times, the similarity of Trump’s and Modi’s political vocabulary is striking. Modi fed the perception that India’s feckless leaders had failed to allow the country to reach its full potential. And he campaigned as the only one capable of fixing that. “I will make such a wonderful India that all Americans will stand in line to get a visa for India,” he said once. A centrepiece of his agenda is the “Make in India” programme.

“It’s all about India first, or ‘Make India Great,’” said Sujeeth Draksharam, a civil engineer from Houston who supports Trump. “Look at Donald Trump. It’s the same thing. ‘Make American Great Again’ — strong again.”

Another similarly powerful sentiment that both leaders have harnessed is grievance. Trump has seized on how the working class feels out of place and left behind in a country that is changing demographically and economically.

Even if Modi’s appeals were never as crass as Trump’s, his followers say he always understood that many Hindus felt their concerns were ignored by India’s secular and, in their minds, deeply corrupt government, which Modi vowed to clean up.

“One of the things that Modi very subtly articulated, but was very clear about, was something which nobody wanted to say,” said Subramanian Swamy, the BJP MP who is often a thorn in the side of the country’s political elite. “And that is that Hindus, despite being 80% of the population, feel like they got a raw deal.”

There are important differences: Modi has maintained good relations with US President Barack Obama and is a proponent of free trade. Still, Swamy said, when nationalist-minded Hindus hear Trump, “they think that this guy talks the same language.”

And Trump’s Hindu admirers accept him, controversies and all. How can he be anti-immigrant when two of his three wives have been immigrants, as one recently told India Abroad. Why should he be punished for singling out Muslim terrorism when, as Draksharam said, “you’ve got to call a spade a spade.”

Reclaiming the grand Hindu pastManu Bhagavan, who teaches South Asian history at Hunter College, said the Hindu nationalist movement in India and its devotees in the US shared a belief that what was once pure and virtuous about Indian life has been tainted.

“They locate this in a grand Hindu past,” he said. “If you go before Muslims entered India, before all these foreigners came in and messed things up, Hindus could do this, Hindus could do that.”

The response, Bhagavan said — whether in India, the US, Britain or any of the countries experiencing a convulsion of anti-globalism right now — is “let’s barricade ourselves in.”

“These problems are all stemming from these immigrants, these different people, so let’s get rid of them,” he said, describing the views of many nationalists. “And it’s easy answers to not such easy problems.”

But perhaps the strongest link between Trump’s speech and the Hindu nationalists who find his politics so comforting is the issue of terrorism and how bluntly Trump is willing to confront Muslim communities about it. Terrorism committed by Islamic extremists is a scourge that has rattled India as well, from the 2008 attacks in Mumbai that left 172 dead to the Uri attack last month that killed 19 soldiers.

Trump’s brand of tough talk, scholars said, gives some Indians a sense that he would be much harder on the country’s longtime adversary, Pakistan. “What Donald Trump articulates has given them some food for thought,” said Harsh V Pant, a professor of international relations at King’s College London. “If there is a Trump presidency, then there might be a stronger Washington policy vis-a-vis Pakistan.”

Kumar, the Republican Hindu Coalition founder, said neither he nor Trump was naive about the fact that most Indian-Americans vote for Democrats. But there could be a few, he said, who may hear Trump and discover his message is not all that unfamiliar.
