It is reported that Yuri Gagarin, the first cosmonaut in history to journey into outer space, commented while looking at our planet from high up above: “the Earth is beautiful, without borders or boundaries”. We don't know if this really happened or if it is just over-romanticisation only good for posterity. Yet, we are sure about the situation down here. The Earth is fragmented into about 200 independent countries and each of them has sovranity over a specific piece of land. In some cases the area is vast and almost endless, in some others it is so small that you can hardly spot it on maps and globes. Each country traces a line to claim its property and to identify itself among its neighbors. “This is our border”, they say. Many things may happen around this line.
