There's not actually any risk, as plainly evidenced by the fact that the State Department has never even given a light wrist slap for any of the dozens of incidents mentioned in the top comment, under Bush, Obama or Trump. There's literally nothing Israel could do to cause the US to "cut ties", let alone even meaningfully rebuke them. Like his buddy Donald, Bibi could shoot someone in the middle of 5th Ave and nothing would happen. US security and energy interests are simply too entrenched in supporting Israeli hegemony.
