US President Donald Trump addressed the UN General Assembly in New York today. Trump made his case for keeping pressure on Iran, which comes in the backdrop of the attacks on Saudi oil facilities. He also talked about the situation in Hong Kong and the tariffs imposed by the US on China. The US president's speech to the UN General Assembly is always one of the highlights of the world body's annual get-together. But Trump is an awkward fit at an organisation designed to collaborate over the planet's problems. Last year, Trump boasted that he had "accomplished more than almost any administration" in US history. Diplomats laughed. The US will hold its presidential elections next year.
