Yes, but haredim/ultra-orthodox jews are very poor, have a strong disdain for technology, and absolutely refuse to go to war. They're even exempted from military service, which upsets greatly "normal" jews, that have to spend 2.5 years doing it to make up for them. Do you think they would be able to sustain a war effort against the whole middle-east ? Well,
Israel convinced most of them to take the vaccine, so nothing is sure.
Haredi jews were expected to reach 40% of Israeli population by 2065.
However, the fertility in haredi jews is slowly dropping too : the average number of children per ultra-orthodox woman
dropped to 6.9, from its high of 7.5 in 2003. They are marrying later, and pursue higher education more and more. Will ultra-orthodox jews continue to exist as a breeding stock for Israel in the near future? I don't know much about statistic calculus, so I'd like to have your insight on this.
Also, to finish on a goofy note, they're having ultra-orthodox kids trooning out and getting worldwide media coverage.
