I suspect that currently the US national interest - as defined by its ruling class - is to keep Israel doing exactly what they have been doing. Because, as I agree with Jerome about the self-reinforcing belief of AIPAC power, I would guess the reason noone has popped that bouble is because it is handy.

If we assume that the US government is supporting Israel because it wants too, then there is two layers to answer any critique:

1. We have to help poor Israel (works great with the blood-thirsty arabs narrative).
   
2. Even if I (as a politician) wanted too change policy, AIPAC would bury me, so change is impossible.

Then not only is the dog wagging the tail, it is also blaiming the tail for it.
