A man is nude in a designated nude beach in France. A man in England with a good telescope views this nude Frenchman. Is the Frenchman in violation of England’s laws against nudity because he can be seen from England?

The answer is, “Of course not”, and the reason why is a large army with the words, ‘Armee de Terre’ on their uniforms. The only laws are enforceable ones, and if you try to enforce your laws on another country without their say-so, that tends to be what they call a ‘casus belli’.
