Trump's UN address: Erratic posts raise global questions

President Donald Trump is set to address the UN General Assembly on Tuesday, with his recent erratic social media posts raising global speculation about the tone of his speech. Historically, US presidents have used this platform to project seriousness and a positive vision, but Trump's past addresses have been divisive. Trump's recent posts have included plans to convert a controversial Washington arch into a military storage facility, a defense of artificial intelligence, and a list of his "Top 25 Trump Achievements." His previous UN speeches have featured attacks on allies and the UN itself, suggesting a non-divisive message is unlikely. The address comes amid an unpopular US war with Iran, which has spiked energy prices and hurt Trump's approval ratings ahead of November's midterm elections. Iranian President Masoud Pezeshkian is also attending, and a potential snub of Trump could further inflame his rhetoric.
