I'm not so sure that the U.S. will ever appear on the Red list again. If you look at the latest from the WHO and the Economist about future travel - the general commentary is that these lists are unsustainable and make very little sense now we know more about the virus. If you already have a strain well embedded in your country, it makes little difference at this point restricting travel. Number of cases are less important when you are moving in to a phase of "living with the virus". For a host country, the only real metric that matters at this point is hospital admissions - albeit the U.S. are struggling there too. Delta is now the predominant strain in the UK and the US and is well in general circulation, so restricting the movement of people internationally doesn't really change this in a meaningful way. Where travel restrictions and travel bans can make sense is where you have a new/unknown strain and you want to slow the introduction of it in to your country (slow, not prevent - it will eventually arrive, and spread).
Hence I think we are moving in to a phase where countries are going to reevaluate the usefulness of travel bans - and I suspect we will start to see this become based on new strains of concern, rather than case numbers. Obviously my two cents as an expert in none of these things
