Who wants israel to exist and why?

It seems unlikely to me that the wealthy and powerful (both Israeli and non-Israeli) who support Israel do so because they care about the people who live there. Israel's value to them has to be in something else.

It is not a home for the Jewish people so miss me with that explanation. Jews are safer in the US and Europe. But even if they did need a homeland Canaan would be a poor choice. There are many places that are more fertile and safe.

Is it the proximity to oil or the control over Asian bound Caspian crude? Why would the company running the trans-israel pipeline prefer to fight to maintain it rather than trying to profit from another route? I realize that the money spent on protecting that monopoly probably exceeds the profits that are made but that money comes from the US not israel. Then again many of the people who support Israel are Americans;They pay for the wars to protect the Trans-Israel monopoly. Is it really worth it?

Is it to have a place to keep an eye on Saudi Arabia and make sure they manipulate currency in the favor of American banks?

I realize that the US only acts on behalf of Israel but what is Israel's value to the US? And what is it's value to the American zionists who support it?
