Taking a longer view, mainland Europe’s safety track record for Jews is limited to the last 70 years, after 2,000 years of being prime targets of prosecution. True, some locations as you mention have a couple of hundreds of years. Hope it continues, but, historically speaking, Europe is not yet a “safe place”. 1913 Europe was viewed by humanity as safe, and with current events we see how unstable things might be. Anyway, we should cherish any place where we, and other people, can have shalom, and not advocating Hashem’s tzitzum to just 2-3 cities. The more, the better.
