Basically his position, when you strip out the inflammatory rhetoric, is that the US wants to keep Israel weak and dependent on US aid. i.e. Get Israel to make concessions (say returning the Sinai to Egypt), the US covers up for that with aid, but the aid can always be withdrawn (say if Israel dares make the US upset, or if some radical President is elected), leaving Israel dependent, and at risk in the long term.

I don't think that accurately describes US policy anymore, if it ever did. Modern day US administrations have withdrawn from the world, and that means their ME policies are not determined by reality, but by domestic ideologies and domestic political considerations.
