Your falling into the government trap of it pushing most of the blame back onto the public in an effort to shield itself.
Do the public bare some response-ability for the spread of Covid?, yes absolutely, a significant minority are not obeying the rules and that is having an effect.
But the current government in the UK has consistently botched many aspects of the handling of the pandemic.
Just to name a few off the top of my head.
Firstly it opted to try to implement a herd immunity strategy which it had to back peddle after a week or so allowing the virus to spread and squandering the three week infection lag it had to mainland Europe which is could as advanced warning to make decisions on.
Then it failed to ramp up testing for ages, consistently failing to achieve its testing targets and lying about the numbers tested.
It failed to get the required number of contact tracers in time.
Botched the importing of PPE from Turkey.
Declined to work with the EU on securing medical supplies due to Brexit mentality.
Inconsistent and conflicting messaging.
Consistently ignoring the scientific advice, countless back tracking on public health measure. This isn't criticism in hindsight, the opposition and the media have pointed this out before its happens. Starmer keeps pointing out in PMQ's that Johnson needs to follow the scientific advice and implement the restrictions when they are asked for, not weeks later.
But Johnson just consistently dithers and delays, and only implements the advice weeks later when the damage is already done.
Then is their other stuff like the "World Beating Tracing App" and "Project Moonshot" and Johnson claiming the UK is among the best or the best at the world in its handling of the pandemic. Odd claim when the UK has one of the worst death rate and poorest economy purpose of nearly every major economy in the world.
I'm not sure why you're listing other countries, yes they may have have handled the pandemic badly or are covering up the true numbers, but that doesn't excuse the UK governments handling of the pandemic.
Its not that I dislike Johnson for Brexit as the reason I criticize him and his governments handling of the pandemic, though the UK's arsing about in the Brexit negotiations over the course of last year no doubt distracted both the UK and EU somewhat from dealing with the pandemic. I'm basing my criticism on the evidence, sure any government can make a mistake but the level of consistency in making mistake by Johnson and his government have made goes well beyond trying your best and failing, it shows ineptitude. Absolutely governing a country in a pandemic is a massive challenge even for the very best leaders and no country has come close to get everything right. Many countries across the world have made mistakes with this pandemic my own country included and again not everything bad relating to the pandemic in the UK is the governments fault. But I do think the UK government most take a huge share of the blame here.
I also understand where you coming from when you say bitching about it doesn't help and constructive criticism is indeed more helpful. But when are you allowed criticize the government or do you have to remain silent even if you believe the government will continue to make mistakes.
