Lol, I've heard it all now. Governments and policy evolve, there was no precedent for this Government to learn from in the modern day. They've made mistakes but hopefully they will not repeat them in the future, their handling of the vaccination roll out is nothing short of outstanding.
I think ISIS probably "learnt" from Goebbels, you know, ethnic cleansing, intransigent views on race and religion, etc, they got what they deserved, their organisations wiped out (hopefully) and death to their leaders.
