1, The first wave of Ashkenazim moved in the same time as the first wave of Sefardim, as soon as the Muslims defeated the Crusaders, and allowed Yidden to move back into Eretz Yisrael (which thanks to the Crusaders had become Judenrein for the first time).
2. The Hareidim were quite content to live under Muslim rule, and indeed the early zionists didn’t object to the Ottomans. My guess is if the Hareidim become a majority of the non-Palestinian population (I didn’t say “Jewish” since an increasing number of Israeli “Jews” are actually goyim), they will cut a deal to end the war. Before this happens, probaby by the end of the 21st century, the zionists will probably make an effort toget rid of the hareidim, one way or another.
