Politics aside, what is Israel's value to the United States?

Technically we have never gone to war over Israels sovereignty so its hard to say we are willing. Israel honestly doesn't need our help in the sense of military man power. Of course its a nice place to test our latest military technology. Israel also has a good share of economic stability and makes it a good strategic ally in the region. Israel is also a technically developed nation, in fact Intel does a lot of work out of Israel, and they are very creative in the sense of security. Plus they are a faithful ally that has been by our side and i don't believe that will change.
