n0, I wholeheartedly agree. It is still an open question whether we can survive with best education while in full contact with the rest of the world. Some communities bet yes, some bet no. I don’t know.
I hope we can … but always chose a safer alternative for my kids.
Note on Sephardim – Arab countries were not touched by modernity. That is different. When Sephardim were in Sefarad proper, they was assimilation even before modernity. Jews in Russia did not assimilate when they were sent forcibly to the army, but did when offered attractive alternatives … so, environment matters … R Shach writes that if Arabs welcomed early Zionists, they would have all went to Cairo University and intermarried. Something to take in mind re: current events.
