Jews have been "hated" since "they killed Christ"
Most likely longer.
Jews, like Romani, have all been viewed as dishonest, larcenous,. (much like Persians are named as liars from centuries back)
Jews were disowned, in many countries. Unable to own property, or anything they could not carry.
So Jews took up the traveling trades (Law, Medicine, Jewelry, Banking)
All trades that have been viewed with suspicion over the ages.
Regarding Israel itself. They Abandoned the land for 1000± years, then suddenly demanded their homeland from the current occupiers. They were allowed to settle. The British Empire during ww2 secretly promised the land to Jews, AND secretly to the Arabs if they would help in the war.
After the war the Brits continued to occupy the Colony, and the Jews took up arms (Terrorist) to free it for themselves.
The only reason the state of Israel exists is because the U.S. (c. 1950) exercised its powers against the rest of the world to "Recognize" the State of Israel in the United Nations.
It continues to exist only because of its relationship to the U.S.
