In the blog post, Cory Doctorow discusses the geopolitical implications of Trump's presidency, arguing that his chaotic policies have undermined America's role as a reliable global leader and escalated tensions. Trump is compared to an untrustworthy escrow agent, drastically altering global trade and diplomatic norms while other nations are prompted to seek alternatives. Doctorow examines how this transition may lead to new systems of international relations and questions the sustainability of American dominance in military and economic matters. He suggests the real challenge lies in adapting to a post-American world rather than focusing solely on technological issues like AI.
