You're correct in that Israel doesn't have a hold over the US (it would be silly to assume that a pissant country could have the resources to control the [at time of writing] most prominent country in world), but they are a US client-state and thus receive preferential treatment when it suits US foreign-policy in the Middle East.

I can agree with this statement. If anything Israel does whatever the US tells it to do and is completely dependent on US support. client-state sounds like a reasonable description of the current reality.

It could be either way around, really. On the one hand, Israel has no military force apart from what the US gives it. On the other hand, Israel has the Epstein tapes (not the files) so it might be rational for a majority of US politicians to just do whatever it asks for.
