Representative imageIndian-American Congressman Ro Khanna on Monday described Donald Trump as a a "lame duck" president and blamed his "utterly destructive policies" for pushing US-India relations to their lowest point in three decades.Expressing confidence in his party's prospects, the California Democrat said the Democratic Party would regain political ground in the coming years. "The Democrats are going to win the midterm elections and the 2028 presidential election decisively," he said.Addressing the US-India Strategic Partnership Forum Leadership Summit in Washington, Khanna claimed that during a recent visit to China, India's ambassador there told him that Trump's policies had eroded a generation of trust between New Delhi and Washington."Now, you know I'm not one to mince words. I sort of tell things as they are. The US-India relationship has been at its lowest point in the last 30 years," Khanna said.Criticising Trump's handling of the conflict with Iran, Khanna said, "Trump's policies of getting into a war with Iran have been utterly destructive. It has been utterly destructive to the prices of gas in India. Talk to (external affairs minister S) Jaishankar if you don't believe me."Khanna also claimed that during a recent visit to China, India's ambassador there told him that Trump's policies had caused long-term damage to bilateral trust."I was in China, and the Indian Ambassador there told me that a generation of trust has been lost by President Trump. If we don't speak the truth about the damage this President has done...we are not living in reality," said Khanna, who is widely seen as a potential Democratic presidential contender in 2028.The congressman also attacked Trump's broader foreign policy approach, accusing him of abandoning America's moral leadership on the global stage."Now you have an America that has forgotten that moral vision, that has a foreign policy of might makes right, threatening not just Iran, threatening Cuba, threatening to conquer Greenland, and we were having dinner as if everything is normal," Khanna said."Who cares about the partnerships of this and that when this President is literally destroying America's leadership in the entire world," he added.Khanna further criticised Trump's immigration and visa policies, arguing that they undermine America's ability to attract global talent."The demagoguery about immigrants, the demagoguery of this President and talking about the lack of immigrants coming into the United States. How can we sit here and not condemn his policies on what he has done with student visas, with the demonisation of talent coming to the United States," he said."38 per cent of the top AI researchers are of Chinese origin. 72 per cent have foreign degrees. This is a President who doesn't understand that we need to be recruiting talent, not turning talent away," he added.
