> Sobering, really, that despite all the ascendance of new powers (who do not yet share the norms) and the noble aims of the old (who are too weak), one year after the US left no one has filled the gap.

One year isn't a lot of time to fill a gap that was previously filled by decades of hard work.

Maybe if the US had had a transition plan, other competent and capable countries could have better filled the gap.
