Good summary.
Just for the sake of my own country of birth, Germany, I'd like to add that MOST OF THE TIME Germany treated Jews better than everybody else did. That is why most European Jews eventually moved to Germany, started speaking German (Yiddish), referred to themselves as Germans (Ashkenazi in Hebrew), and spread eastwards, still clinging to the German language and German traditions. Some orthodox Jews still speak Yiddish at home because of that history. In Germany, Jews often had the same rights as other citizens. That was unheard of in Europe at the time (and is, except for Bahrain and few others, unheard of in the Arab world).
Germany was once a safe haven for Jews, before it became hell on earth for most minorities.
(The French Dreyfuss affair shows how much Jews were associated with Germany at the time.)
But it is true that anti-semitism has been with us for a long time and few nations managed to get rid of it. Currently, the US have managed and have been quite stable. Germany managed it in the past, but was caught again.
The international community (whatever that is) still has much to learn.
How often has the UN General Assembly condemned wars by Arab countries against Israel with the goal of completely destroying that country?
How often has the GA condemned Israeli attempts to survive such wars and prevent new attacks?
