Israel and Palestine

Surrpoting Israel is not a Christian command. It is a evangelical church command. Because the existence of Israel is a prophetic requirement for Jesus to return and start the apocalypse. Also surrpoting Israel is not free of antisemitism as many Christians love Israel but hate Jews.

But Jesus or God gives no commands for supporting any nation. He does say to render under Cesar what is his and God's what is God's. And Israel was under roman occupation at the time.

He also states the greatest commandment is to love God and each other. The bible also says that love covers a multitude of sins as it was the love of Jesus that death the gates of hell when he gave up his life to save another. And no one has greater love than one who would lay down their life for another.

Also God is described as synonymous with love and those who don't have love do not have God. So make sure you are following love. Not "God". Because religion has twisted the word God to mean whatever they want it to mean at any particular time.

I would suggest learning more about the history of the entire area and how one thing led to another in a row of dominoes that go back into prehistory. Because this seems to be a war that was happening even before the existence of writing no one will ever really know who threw the first blow. At this point the problem is endemic to the area.

I would also suggest to be extremely careful about "christian" sources as religion attracts evil people as they are attracted to the position of authority and power. There is a movement in some christian circles of deconstruction which is a re-examinination of faith and rejecting old ideas that are of no use or harmful to the person or the world as a whole.
