It’s certainly an amusing thread to read, the US has more power, no it has less, China is pulling ahead, actually it’s struggling, so is India, or not.
China is not without problems and had some problems in economy. This situation allows them to get ahead, internally plausiy blame Trump even for issues that existed even before, get new aliances and power.
America is not gaining power, that part is pure wishful thinking.
If only there were numbers we could compare.
