I disagree, you can lay the blame for Brazil’s performance absolutely squarely upon Bolsonaro.
Just as you can lay the blame for the relatively poor performance of Sweden compared to its neighbours squarely upon Tegnell.
We can go further, the US performance can be squarely laid upon Trump.
Whilst folk might say that one person is not a government and lots of enablers have also contributed to these failures I would argue that if you remove those individuals from the original onset of the pandemic and left in place all the others then the responses would be magnitudes less serious.
In the case of Bolsonaro in particular, he has gone through many ministers who have either resigned in protest, or he has dismissed them for failing to follow his incompetent lead - the Brazilians have argued many times that Brazil faces two pandemics - Bolsonarism, and Covid and they are not selecting either as the worst one.
As for India, too much attention is given by most pundits using numbers as scary headlines so generate more mouse clicks, but the fact is that when you compare like with like, India’s relative numbers compared to it’s population size are way better than the vast majority of nations - look at the Worldmeters data and you’ll see that their death rates and infection rates per million are magnitudes less than most of the world - even if you allow for serious under reporting India is still faring far better than the vast majority of the world.
