I think the influence of Israel over the US politics has been exaggerated to some extent.
The US allows Israel to do what it wants to do because the US wants to maintain order and the status quo in the region, not the other way around. Israel has successfully suppressed every resistance movement in the region for decades. Without Israel, the US would've been dragged into perpetual wars in the Middle East to control the resources of our region. There's no doubt that this is a win-win situation for both the US and Israel.
Sure, Jewish billionaires buy politicians in the US, and they control the media, Hollywood, banking, financial systems, etc. but at the end of the day, the people who are in actual control of the US as a whole are Americans of European origin, mainly WASPs.
