"World opinion" is generally moral blackmail,and those who are fighting for decency will be able to fight better once they loosen the chains of "world opinion". Let the "world"(most of whose opinion matters less than nothing) go circle jerk.
"World Opinion" is simply journalistic opinion, hyped by journalism. Journalism can properly be spoken of as a unitary entity for the simple reason that journalists obey the "eleventh commandment" - "Thou shalt not question the objectivity of a fellow journalist."
