"He addressed the whole world to inspire hope in liberal democracies ..."
But if he had been honest he would have admitted he (in two years)  has done nothing to change the dismal picture he painted. That is what virtue signalling is - just talk. In Africa he left a meeting where he was lecturing leaders on LGBT rights and went straight to a podium to praise Fidel Castro, one of the world's worst offenders in terms of persecuting gays. More posturing, more virtue signalling. Or the Paris Climate Conference where he claimed that Canada was "back" after flying 400 people there on carbon spewing jets - then keeping Mr. Harper's 2030 goals. (Also Harpers health funding formula after lengthy criticism in opposition.) He's long on talk, pretty short on accomplishment - a poseur.
