You're reading things OP didn't even write; and addressing a historical assertion with present-day facts.
OP posits that European settlers coming in during the Ottoman era (establishing Hebrew-only areas & businesses, only to later demand a Jewish State, in opposition to the local majority [0]) is what kickstarted the current conflict. It isn't a 1000 year old feud.
Mizrahis, save for Yemenis, migrated en masse after the conflict was irreversibly set in motion by Imperial Britain & various Arab states.
