Why?This is mind boggling.
Why is the US acting like this (or parts of it).
The most effective thing to get the US to change right now I think is for every other location in the World to ban travel to and from the US, but more than that...ban ANYTHING AND EVERYTHING coming and going from the US until the virus is under control. That would probably change their tune within 1 or 2 months (hard heads are hard to convince).
If the US says it's about the economy, then shut the economy down and that argument no longer has any legs to stand on.
I'm not sure how to make the US see more sense, and I am unfortunately in the heart of it (as many of us are).
Because entities internal and external to the United States benefit from chaos, infection, fear and divisiveness.
It's not hard to be further divided once you see a % of the populist is bigoted nutjobs. Kinda hard to ignore that.
Meanwhile, cutting off the US. What do you hope to achieve? Mask wearing? Self isolationing?
Don't forget that the USA fought WW2 on two fronts using all its own supplies and manufacturing. We have tons of resources. Not much manufacturing anymore, but a world quarrantine of the US would encourage us to spin up all that stuff again and make people go to work. Exact opposite effect.
Add to that, resentment against the world. Worked great for Germany post WW1. By great, I mean that's how evil starts. Got good.
