Imagine which places where waves of omicron just recently swept through almost the whole population and thus will get near immunity from this.
I think you grossly overestimate the capacity for rational thinking of the average American. The restrictions are not meant to be effective, they are just theater acts meant to associate China with the latest COVID wave.
XBB has already been endemic in the northeast of the U.S. over the past several weeks.
Totally not the same. China’s policy doesn’t single out any particular country.
You are correct, but due to initial surge China will have a higher proportion of infected compared to basically anywhere else for a week or two before it returns to world baseline infected percentage. So from a populism perspective, its a sensible choice to placate the masses after demonizing China for years.
How could China do this.
Then again, there aren't signs it's any more dangerous than run of the mill omicron, looking at US stats there currently isn't a massive spike in deaths or anything, so even if it is more likely to evade vaccine and infect you if you survive omicron you should be fine with the new variant also.
