Germany and the UK are incomparable when it comes to athletics. You can go to any DL or Gold Label meet and not see any German athletes at all. They have two world class athletes in total (Koko and Mihambo). The UK has global medal contenders across multiple events, names you'll see at the highest level meets: Kerr, Wightman, Muir, Hodgkinson, Johnson-Thompson, Asher-Smith, Hughes, Hudson-Smith.
Norway and the Netherlands are doing OK, but they're reliant on a handful of generational talents. Once you get below Jakob and Warholm in Norway, and Bol and Hassan in the Netherlands, there's not a lot of depth, just the odd athlete like Nordas and Laros. It reminds me of Sweden in the early 2000s when they had Karolina Kluft, Christian Olsson and Stefan Holm winning medals. They were just huge talents, there wasn't a system behind them to being more through.
Britain won 10 medals in Budapest, Netherlands 5, Norway 4, and Germany 0. Spain won 5 as well but two of them were for race-walking
