The Jewish people do not deserve the treatment they have received from Christians, Pagans and others over the time Judaism has been in existence. All religions are just in the current parade history and will one day be gone.
Today, support for the existence of a Jewish dominated Israel is falling out of favor among younger generations. The link defends current Jewish Israel by telling us young people need to learn of its God-sponsored origin. That seems like asking younger generations to take something that is a myth so far as we know and treat it as actual history.
My impression is the Christian support for Israel originates from the home offices of Christian denominations. If there were no denominations I doubt there would be as much Christian support.
Support that comes out of the U.S. is also generated by political areas with older Jewish voters. The question now is whether U.S. support by Jewish people will extent into future generations.
When we see how unsuccessful democracy has been in the Middle Eastern countries we invaded it is a lesson in how hard it will be to maintain in Israel.
Countering the claims of Jews that Israel was given to them by God is the claim of Palestinians. They say writing from seventh century BCE puts them there and that they descended from the areas indigenous people .
I think things will remain as they are until demographic change drives Jews and Palestinians to some different relationship.
