"If you see a border cross it, then turn around and you will see that it never existed." Those words I heard from the jurist Michele Taruffo. He joked: "I took them from the apocryphal diary of Genghis Khan".
The term boundary is used to refer to the limits drawn between one country and another. The borders are always conventional, although, in many occasions, one of the parties was the weak one in the Convention. The borders move depending on the power of one country with respect to another or others. This is how new domains are assumed.
There are invisible borders, others very marked; there are friendly borders and others that are offensive and threatening. By the fictions of law, if I cross a border, I cease to be a national and become a foreigner.
