It doesn't have to be either non democratic China or blundering idiot Johnson.
Within a democracy isolation and mitigation measures can be put in place to slow down the spread to manageable figures, or even to virtually zero.
But governments have to consider minimizing the impact to livelihoods and ensuring that people comply.
From my experience here in Portugal, with exceptions, the community spirit is working well and social disapproval has had a strong effect on social behaviours.
I'd say that for the most part, society has been ahead of the government in asking for stricter measures.
I don't know how this will pan out, but one thing is for sure, this will set apart the Churchills from the Chamberlains.
