Israeli Jews are not having enough children to replace themselves. They're so desperate to boost the population, they're even rolling out the red carpet for Ethiopian Jews now, in contrast to how they reluctantly took them in in the past, initially refusing to because African.
They've been treating Sephardics better too, as they were always treated as second class. But since the Sephardics have more children than Ashkenazi do, the Ashkenazis realized that in order for the country to survive, they're going to have to treat their own fellow Jews as equals. Almost.
Talk about anti-sSemitism, European Jews looking down on Middle Eastern Jews, and the Middle Eastern Jews have a lot more Semitic DNA than those Eastern Europeans that have only 30% Jewish blood.
Regardless, just like in America, their population will shrink, and they will become increasingly dependent on Palestinians to do their labor and feel other jobs left vacant. It's going to take a couple generations, but eventually Israel will cease to exist.
