International relations are often framed as a zero-sum game, where one country's gain is another's loss. Having lived in three countries and worked with global teams, I've seen how cooperation on climate and trade actually benefits everyone, yet security rivalries keep pulling nations apart. Do you think the zero-sum mindset still dominates the real world of diplomacy, or has interdependence truly reshaped how states behave? I'm not sure either, given the rising tensions between major powers like the US and China, but the data on shared economic growth suggests we're not purely adversarial. What's your read on whether we can move beyond this old paradigm?
