"I tried to connect my favourite space cowboys to space countries of our world and their features. As I thought, USSR, USA and China are the only countries, who had made their piloting spacecrafts, as Jet, Spike and Faye are the ones, who had their own spacejets on Bebop (I get it while was writting this, hehe). Also, USSR was the first one to start space race with their "sputnik", USA has joined them later, China even later. Spike also has joined Jet at his spaceship, and then we know they have met Faye. Japan is one of the technology leaders (hi, Ed), and Poland as Ein is just a reference to "Poland can't into space" meme of pollandball community."
