"To get to Earth from the edge of the solar system, depending on the time of year and the position of the planets, you need to pass through at least Poland, Prussia, and Turkey, and you'd probably get stamps in your passport from a few of the other great powers. Then as you get closer to the world, you arrive at a point, in the continually shifting carriage space over the countries, where this complexity has to give way or fail. And so you arrive in the blissful lubrication of neutral orbital territory."
