Answer:The Global Interstate System is just how countries deal with each other. Like, how they trade, make alliances, talk things out (or sometimes fight), and basically try to exist together on the same planet.It’s all about the relationships between governments who’s friends with who, who’s beefing, who’s doing business, who’s helping who during a crisis. And yeah, some countries have more power than others and kinda steer the direction of things.So when you hear about stuff like the UN, wars, peace talks, international trade, or global issues like climate change that’s all part of the global interstate system.At the end of the day, it’s the world’s way of trying to stay connected (and sometimes just keep the peace).
