But without Arabs....Jews already exterminated long ago by christians.

Arabs vs Jews is a new thing.....

Without Arabs taking palestine in 7th century from Byzantine christians....jews will be eradicated long time ago

But it's true....jews are relieved that they have been liberated from Byzantine oppression....they even fought together with muslims to defend Jerusalem against crusaders.

The majority of European jews before WW2 was Ashkenazi, which may originated from a small community of jews in Germany... because significant portion their genetic is European

It is disputed whether Ashkenazi is true jews, because significant European admixture in their gene, so they might be originated from a small group of jews who migrated to Europe and their jews genetics have been significantly diluted.

Ashkenazi is different to pure blooded jews who remained in Palestine.

So, the conflict today, is essentially Arabs vs Europeans with little jews genetics....because Israel today is dominated by Ashkenazis who migrated from Europe.
