If you're speaking about 20th century behavior, I think the Church's main concern has been for the Christians in the Holy Land, although I agree that the popes don't seem to have supported Israel adequately against the Mohammedans. But this is a matter of prudential judgement, not doctrine.
Also, keep in mind that the Church helped save thousands of Jews during WWII. "Hitler's Pope" had such a great role in protecting Jews during the war, that the then Rabbi of Rome converted to Catholicism, and took the pope's name as his baptismal name.
To rephrase, do you think that throughout history the RCC has constantly been strongly supportive of and reaching out to the Jews, dispersed and now returned to their God-selected earthly homeland?
BTW, RCC has claimed credit also for the helping of Jews during WWII performed by many other non-RCs.
Your posted story of the Rabbi of Rome’s conversion is understandable.
That’s your entire response? I hope for better and more.
