What are you talking about? The US is at the top of the handling of the crisis. You could definitely critique Trump and the fact he can't keep from saying some of the most ridiculous and petty things, but even Gavin Newsom has complimented the way this has been handled. If you only ever look at top headlines, you'll believe the world is about to end and Trump is responsible.
Also, how is Trump responsible for Italy and Spain? Or are you so xenophobic that you believe that only the US could possibly have handled this for them? Italy and Spain listened to the WHO and they suffered and continue to suffer because of it. Trump didn't completely listen to the WHO and saved lives. Now, maybe he should have closed things down earlier and followed the Taiwan and South Korea models, but those countries did well because they didn't listen to the WHO and knew China was lying because of the last flu outbreak.
Do I think Trump is doing A+ work, no, but I can see that the US is doing much better than many other countries. And when you say that Trump is doing a bad job, you do realize that there are teams of people working on this. So you are saying that everyone who's working on this crisis is mishandling everything? If it's only Trump, what do you think he did wrong? You might say he downplayed the pandemic, but everyone did. And if you think that, what should he have said? It's easy to use hindsight and say people did these things wrong. I think everyone is doing the best they can.
I'm really tired of seeing this criticism with no evidence and with other countries that clearly did a worse job. I don't think it's fair to blame the leaders of those other countries either, when it's pretty clear that China and the WHO deserve a lot of the blame.
The WHO is not a scapegoat, they are directly responsible for thousands of deaths, and untold suffering. They may have done it because of their close ties to China, and they may have believed what they were saying, but at this point would you trust anything they say?
