Trump shut down access from China, and then from the EU, apparently a bit of a shock to Merkel, who thought there should have been multilateral negotiations over it. Biden and the AOC crew were loudly decrying any reaction that involved singling out China as "xenophobia". IMHO, he's done a stellar job. He's not perfect, and can't anticipate events. I don't think anyone really can. So far, though, he's reacted in a timely and cautious manner, and has even been ahead of the curve a few times. There's not been another POTUS during my lifetime that I trust so much to do what he thinks is the right thing, regardless of what anyone else thinks.
