The Nobel Prize and a Testy Phone Call: How the Trump-Modi Relationship Unraveled

Prime Minister Narendra Modi of India was losing patience with President Trump.

Mr. Trump had been saying — repeatedly, publicly, exuberantly — that he had “solved” the military conflict between India and Pakistan, a dispute that dates back more than 75 years and is far deeper and more complicated than Mr. Trump was making it out to be.

During a phone call on June 17, Mr. Trump brought it up again, saying how proud he was of ending the military escalation. He mentioned that Pakistan was going to nominate him for the Nobel Peace Prize, an honor for which he had been openly campaigning. The not-so-subtle implication, according to people familiar with the call, was that Mr. Modi should do the same.

The Indian leader bristled. He told Mr. Trump that U.S. involvement had nothing to do with the recent cease-fire. It had been settled directly between India and Pakistan.

Mr. Trump largely brushed off Mr. Modi’s comments, but the disagreement — and Mr. Modi’s refusal to engage on the Nobel — has played an outsize role in the souring relationship between the two leaders, whose once-close ties go back to Mr. Trump’s first term.

The dispute has played out against the backdrop of trade talks of immense importance to India and the United States, and the fallout risks pushing India closer to American adversaries in Beijing and Moscow. Mr. Modi is expected to travel to China this weekend, where he will meet with President Xi Jinping and President Vladimir V. Putin of Russia.

This article is based on interviews with more than a dozen people in Washington and New Delhi, most of whom spoke on condition of anonymity to discuss a relationship that has far-reaching implications for both sides, with Mr. Trump eroding ties with an important partner and India alienating its biggest trading partner as it tries to keep its economy afloat.
