China speaks with one voice, Xi, everyone else a thousand voices. US has 10 000 people at least who make up the power of Xi. President, senator, CEO, senior bureaucrat, judge, heads of NGOs, Universities, police, military etc. all 'put in one group and coordinated with an ambitious 50 year plan' in the West. Even in a single country.
Europe, N. America, Japan, Korea, Australia have to partner with 'everyone else' in a comprehensive way to stand up to this. Trans Pacific was a big opportunity that Trump didn't have the foresight to grasp - he wanted to have 'unipolar power' in a world where the US just does not have the leverage it did after WW2 and no amount of 'wishing' or even exceptional leadership will change that. US could 'solve all it's problems' and it would still be the reality that % of global GDP would be declining because other nations are 'coming on line'.
Oddly, a panacea of 'other voices' may serve to counterbalance. Even if they are acting in self interest, to the extent they are not overrun by China, their own voices add up to something. We are seeing the beginning of that in Africa, with their stance on the Ukraine issue. While they should definitely be taking a more assertive stance via Russia, the fact they are where they are (and partly due to the fact Russia is their 'breadbasket') is an indication of coherent self interest on some level.
I don't think it's cause for world wide alarm, but there needs to be a plan.
