I don't see a US in decline.
I do see a China on the rise. But only really filling the vacuum formally occupied by the USSR.
Does Mr Trump hate China? I wouldn't call it that. He could have imposed travel restrictions at the same time as Vietnam or North Korea or Taiwan.
But held off till the WHO called it, I believe, to avoid a diplomatic incident.
That looks more like someone that wants to be seen to be acting correctly. That the WHO took so long to call it, that got some hate.
Others won't see it that way, nothing surer....
