“When WW1 broke out the Turks expelled any Jew who did not have Ottoman citizenship”
And even worse, the Ottoman Governor of the region that included Eretz Yisrael then tried to do to the Jews there what they had already done to the Armenians. Many Jews had to flee, some even to Egypt! You can even find some articles about this effort in the archives of the New York Times!
The Ottoman Empire, for most of its existence, treated Jews better than most other European countries. But it is not hard to have treated Jews batter than England, France, Spain, Portugal, or Russia, which were Judenrein for much of that period. But had the British Army not arrived in time it is entirely possible that the Ottomans would have done what the Romans and Crusaders had failed to do — exterminated all Jews in the Land of Israel. Excusing the genocidal Ottoman leaders is simply inexcusable.
