Free speech of opinion is not the same as scientific claims without evidence. Regarding Nobel Prizes, most of the US’s dominance was in the past not recently. For example here’s the number the US compared to other countries by ratio: 2019: 2/3; 2018: 5/13; 2017: 6/13; 2016: 1/13. Also comparing per capita wot Germany and UK is misleading. The US has 320 million people, Germany is 82 million, and the UK is 68. On a per capita basis those countries do better.
