For the Jews the messiah is a powerful warrior king who will conquer all nations. He will subjugate the world with the sword and the non Jews will become slaves to the Jews.
This is what the Jews believe the messiah will be. When Christ.came he wasn’t a warrior king or at least chose not to be. And instead healed the sick and helped the poor. This is why they rejected him.
Jews believe they have been unfairly persecuted their entire lives and if you have ever met a Jew you know that their fundamental driving emotion is bitterness.
So to them they believe that the only just messiah is one who gives them the power to subjugate the people they believe have oppressed them.
Why do you think Judaism and communism are so intertwined?
