Hey you asked for something and Tiny responded.
There is no vaccine yet and certainly no "Cure" and probably never will be considering it's a virus.
So that leaves it to simple public health measures such as hygiene,masks,distancing,early testing,and contact tracing.
Those countries that did well dealt with it honestly and scientifically for what it was and in a responsible manner.
That was sharp the way you got in your immigration barb by trying to blame contact tracing failure on "can't control the border".
To put into effect the above mentioned public health measures one of the central tenets is to get the public on board with a concerted well directed program.
That does not allow for the lied to bullshit and the erratic impulsive actions of a president solely focused on his political future.
You notice Tiny pointed out that these countries did better with the virus while at the same time thriving economically.
We did not have to have our ass kicked economically as bad as we have if Trump had dealt with the virus better.
We are a smart,rich,technologically advanced,medically well supported nation and we are well down on the scale of the Covid response list.
Far outdone by what Trump would call shithole countries.
