Terming India a "key strategic ally", Republican presidential nominee Donald Trump has promised that if voted to power India and the US would become "best friends" and have a "phenomenal future" together."Under a Trump Administration, we are going to become even better friends. In fact I would take the term better out and we would be best friends," Mr Trump, 70, told a cheering crowd of Indian-Americans at a charity event organised by the Republican Hindu Coalition."We are going to have a phenomenal future together," Mr Trump said as he praised Prime Minister Narendra Modi for boosting economic growth in India with a series of economic reforms and reforming the bureaucracy, which he said are required in the US too."I look forward to working with Prime Minister Modi," he said, adding that the Indian leader is very energetic. It was for the first time a presidential candidate attended an Indian American event this election season."I am a big fan of Hindus and I am a big fan of India. If elected, the Indian and Hindu community would have a true friend at the White House," Mr Trump said, adding that he has great confidence in PM Modi and India."I was there 19 months ago and look forward to going there many, many times," he said at the event.Mr Trump appreciated India's role in fight against terrorism."We appreciate the great friend India has been to the US in the fight against radical Islamic terrorism," he said as he slammed his Democratic rival Hillary Clinton for not using this word. Mr Trump said India had seen brutality of terrorism, including the 26/11 Mumbai attacks."Mumbai, a city, I love. The attack on India was absolutely outrageous," he said while assuring some 5,000 Indian-Americans at the event that if he becomes the president, the US would "share soldier to soldier together" in the fight against terrorism."India is key and a key strategic ally," he said, adding that he looks forward to deepening and strengthening military cooperation with India.

In his welcome address, the Republican Hindu Coalition founder and chairman said that this is the first time in the history that a major presidential candidate has addressed Hindu-Americans just three weeks before the election.He urged Hindus to support and vote for Mr Trump in the upcoming general election and help fight terrorism.
