I haven't read it, to be honest, but that's what Kant was saying in his "Perpetual Peace: A Philosophical Sketch" (https://en.wikipedia.org/wiki/Perpetual_Peace:_A_Philosophic...). I'd say that even though we're not there yet, we have been getting closer and closer to that ideal in the last 200 years, with the well-known hiccups along the way.
