Normalized by population the worst non-tiny (10M+) countries to be right now seem to be France, Italy, Belgium and Poland. And it'd be even worse in France, Italy and Poland in terms of new cases if they had the kind of testing throughput the US has been able to muster (1.24M tests a day). Belgium has comparable normalized test throughput. As far as cases, new cases = positivity * throughput. The higher the throughput, the more cases you are going to get.
