Once again, @SQUARE_ROOT nauseatingly spouts his love of the Zionist idol and criticizes G-d-fearing Jews (NK) because they publicly deny his idol and also misses the point despite the multiple posts by ujm and others explaining. Amazing how idolatry destroys rationality.
English would have been an excellent choice, especially because that was the language of the Mandate there at the time, and already was an international language. The only reason the heretics bastardized and denigrated our holy language with their creation of “Modern Hebrew” is for heretical nationalist purposes.
It is the Zionists, not anti-Zionists, that were rodfim, as they have amply written and shown throughout their odious history going back over a century.
It is also the Zionists, not anti-Zionists, who have amply proven their VERY LOW opinion of Sephardic Jews, like Yaldei Teiman and all the rest.

The point is to keep the holy tongue exactly that: holy, and to use a different language for mundane day-to-day speech. Yiddish could work for that, of course, though a yeshivish English would probably be the modern equivalent and also not have the baggage of speaking a similar language to that which the Nazi murderers spoke.
