re: Sovereign states
That's the beauty of the principle of non-interference in internal matters of sovereign states:
1) What goes on inside another country is not your business nor your responsability.
2) If it does become your business and you interfere, then:
a) you are responsible for everything that goes on, there.
b) you are being exposed to double standards as you can't do the same everywhere and a question is raised: what is the criteria for interfering and what is not?
