Former U.S. President Donald Trump has reignited a long-debunked conspiracy theory, suggesting that Canadian Prime Minister Justin Trudeau may be the son of Fidel Castro in his upcoming coffee table book 'Save America.' Trump, echoing previous comments, stated during a podcast and in the book that while he and Trudeau have a cordial relationship, their political ideologies differ significantly. He referenced Trudeau's mother, Margaret, who he claims was linked to both Castro and the Rolling Stones, asserting that many believe Trudeau could be Castro's son. These claims have been widely dismissed and refuted by official statements, including a 2018 denial from the Canadian government. Analysts suggest that such rhetoric reflects a broader trend of personal attacks within political discourse, potentially undermining international relations. Trump's remarks continue to draw criticism for lacking substantiation and for promoting unfounded conspiracy theories.
