The 'Letter to America' TikTok trend exploded in late 2023 when users began sharing their reactions to a 2002 manifesto written by Osama bin Laden. The trend typically features a split-screen or POV format where users appear visibly shocked or enlightened after supposedly reading the text on The Guardian's website. It sparked a massive cultural debate regarding U.S. foreign policy and information literacy, leading many platforms to eventually remove the content. In meme culture, it is used to represent the feeling of having one's entire worldview shifted by a single piece of information, often applied to both serious and absurd contexts.
