There are a few who have done well, such as the PM of New Zealand, but most countries have had some successes and some failures, and some are unfortunate enough to have had to suffer idiocy in my opinion, I’m thinking of the USA and Brazil in particular. Others have to contend with secrecy such as China.
Overall I think we’ve not done very well. Lockdown too late, not closing borders, poor provision of PPE, care home management, lockdown not strong enough, blatant breaking of lockdown legislation such as huge crowds gathering, poor testing and tracking. With all that going on we’ve done better than we deserve to be honest.
Having said all that, we have to remember that even the scientists disagree on some things, and even the scientists break the rules. The wearing of masks is an example. Masks help, no they don’t, yes they do, no they don’t. Well I believe masks help to prevent spread and offer at least some protection to me. So I wear a mask when I feel it’s appropriate eg shopping.
