It's not just about the US, it's not just about the Trump, it's literally about every country and every top leadership out there (well, except for China maybe, it was locked completely right after the little spread in Wuhan, but that doesn't really mean that China knew more about the virus than us before December, right? Right?!?).
We should know by now that our president/prime minister/dictator doesn't really care about us (*they don't really care about us!*). In order to keep the economy running, they were ready to let the virus spread by not locking down before. All they wanted was short-term temporary stability in their stock markets and economy. They never realized that if something so dangerous hits the country with a big force, and if they're unable to buy the ventilators for the people right now, the economy will itself be put on a ventilator. It has happened already with about ten countries and is now continuing to happen with others.
