60 million people Americans got Swine Flu under Obama-Biden. Using your logic they are responsible.
You want to compare Covid-19 with the Swine Flu, and their respective impacts on- and responses from the USA..? According to WHO the Covid-19 pandemic is like 10 times worse than what Swine Flu was and it was very quickly obvious that Covid-19 is far more deadlier, and remains potent for much longer (i.t.o. infection, spreading and recovering). If you look at the number of people who got infected by Swine Flu and who died from it compared to Covid-19 (over similar periods), then it becomes obvious that we are talking about vastly different pandemics.
As such and from what I have read, the Obama response, measured i.t.o. risk exposure, was quite adequate. In case you prefer the Trump/Republican spin on it, there are always fact checks such as
this one and
this one.
The last fact check above quotes various experts, among others Dr. Amesh Adalja who is an expert on emerging infectious diseases and pandemics and a senior scholar at the Johns Hopkins University Center for Health Security. Elsewhere he was quoted saying:
What was the US response to swine flu compared to COVID-19?
"There were some mistakes, but it wasn't anything too consequential," Dr. Adalja says, adding that, "once public health officials realized that swine flu wasn't going to be cataclysmic, they backed down on mitigation efforts like school closures and social distancing."
But, Dr. Adalja says it's very difficult to compare the Obama administration's swine flu response to that of the Trump administration's handling of COVID-19. "Whatever faults the Obama administration had with their response to the 2009 pandemic, those are dwarfed by continual errors from the Trump administration that are continuing to this day," he says. Those include, but aren't limited to: failing to take the deadly illness seriously, slashing funding for critical public safety nets, and significantly lagging in testing during the first weeks and months of the pandemic.
