Your comment displays your utter ignorance, as usual Octavia. Well, let's be fair here, that's just my opinion. I assume you're referring to behavioral changes to help mitigate the spread of the virus, right? Such as wearing a mask, social distancing, washing hands, and not touching our face (especially the eyes and nose.)
Those modified behaviors certainly would have helped, had we all got on board in the beginning. But they certainly couldn't have stopped the spread of the virus overall, as those in the media who criticize Trump for not wearing a mask would have us believe. And, doing so wouldn't have changed the reaction from the 'chicken littles' in this country who wanted to shut down *everything*, regardless.
And, just in case you were attempting to make a point about Trump, keep in mind that he was taking advice from the guy in the attached photo. AND even though he was, and keep in mind that according to Fauci, Trump took every single piece of advice given, Trump still shut down travel from Wuhan, China a few days *after* Fauci made the statement he made in the attached image.
And that doesn't even take into account things like Nancy Pelosi going to Chinatown in February during the Lunar New year in 2020 and telling people to come on out and have a good time, and Bill DeBlasio in New York city in March 2020, telling people to come out and live their lives.
Sorry Octavia, but I feel I have to mention those things to pre-emptively stop you from making statements that are factually wrong about Trump, as you are wont to do.
