What if you didn't have internationalism?

Without internationalism, countries would likely become more insular, leading to increased nationalism and decreased cooperation on global issues such as climate change, trade, and security. This isolationism could exacerbate conflicts, hinder economic growth, and limit cultural exchange. Additionally, global challenges that require collective action, like pandemics, would be harder to address effectively. Ultimately, a lack of internationalism could result in a more fragmented and unstable world.
