In Olden Times, when any Non-Jewish Tribes went to war against one another, the Jewish Folks just loaded up their camels and set off for the nearest well-travelled roadway in order to sell goods and financial services to anybody passing by.
The Jewish Folks never really cared which Non-Jewish Tribe won the war. They marketed and sold to both sides of the warring parties. In a sense ..... it was not their (Jewish) fight, it was a fight between Gentiles. And after the war was over, the Jewish Folks would be there to finance reconstruction and be at the throne of power.
And they are doing the same thing today when insisting on an attack against Iran.
The Jewish Folks did not kill Jesus, but they lobbied Pilate in the same way as the Israel Lobby does with the U.S. Congress today (with political and financial support) to kill Jesus. It was not the Romans who arrested Jesus, it was a gang of Jewish Elders who arrested Jesus. The Jews were the folks who brought Jesus to Pilate in the first instance and demanded (lobbied) to have Jesus crucified. The Romans did not see Jesus as a threat to them, but he sure was hated by the "Business Class" or the "Chosen People" at the time.
"Now there arose up a new king over Egypt, which knew not Joseph. And he said unto his people, Behold, the people of the children of Israel are more and mightier than we: Come on, let us deal wisely with them; lest they multiply, and it come to pass, that, when there falleth out any war, they join also unto our enemies, and fight against us, and so get them up out of the land."
--Exodus 1:8-10--
