Here's what I would have done (and what the experts would have done):
Trump banned travel from China on the 24th. Good job Trump. Immediately after that decision, I would have instituted a wide-spread contact tracing program, as well as invoked the Defense Production Act and pumped out as many testing kits as possible. Even before the virus, experts were warning Trump that the US was NOT prepared for a pandemic. Before the virus hit, I would have developed a plan for what the US strategy is in case of a virus.
These steps were taken by countries such as South Korea, who was able to keep the virus at a minimum. Social distancing should have also been mandated far sooner. The complete shutdown should never have had to be enacted. It only happened because Trump waited for so long to address the virus; it was a last resort.
Trump's rhetoric on the pandemic has been horrible from the start. He has not endorsed masks (he doesn't wear them) and he keeps touting Hydroxychloroquin, even though the medical professionals told him not to.
