b. Israeli Jews who have passed on would, presumably, be included in the generic Yizkor/Keil Maleis just like all other Jews from anywhere else who have passed on.
For MiSheBeirachs, too, please cite one halachic reason that Jews in E”Y are more eligible than others to receive a special bracha just for them.
We daven at least twice a week “Acheinu kol beis yisrael haNisunim baTzara uVaShivya…HaMakom yiRacheim aleihem….” and (non-“MO”) shuls and yeshivos across the world daven for our brethren in E”Y daily if not more by reciting tehillim after davening.
not necessary for your point
Incidentally, the prayers invented by the Zionists are, of course, also problematic in their particular wording, so those are anyways non-starters. We obviously have no need for idolatrous (per our gedolim) add-ons to our tefillos.
What you mean to imply is why people don’t accept the A”Z of Zionism that “MO/RZ” have grafted onto, lihavdil, our holy Torah. The obvious answer is that the gedolim strictly forbade this deviancy in the strongest terms.
