Given the benefit of hindsight and a crystal ball they could of done better
"Apart from that, how did you like the play, Mrs Lincoln?"
Britain's biggest mistake was getting off the mark very slowly indeed. WHO published their first report early in the New Year. Australia closed its borders at the start of February, when nobody at all had died. At that stage Britain hadn't even advised people against travelling to China. By the time Britain imposed a lockdown in late March, about 350 people were already dead.
We've been playing catch-up ever since. Countries that got in quickly have had a fraction of the deaths here.
So: 37,400 British deaths. 103 in Australia. Britain has I think got about three times the population of Australia but 374 times as many deaths. That can't just be explained away by population density. It's very poor.
Also, Britain is hampered by being run by a man. Among the countries that are doing okay are Germany, Finland, Iceland, Taiwan and New Zealand - all with women in charge. We shoulda stuck with May :-)
