You are missing quite a bit. It is not obviously quid pro quo in diplomatic relations but on that point you are partially correct. If the US for one reason or another cuts ties with Israel, it loses its main influence in the middle east and other countries would probably quite happily pick up the tap. Only some are from the region, others are not.

All this has absolutely nothing to do with Larry Ellison and frankly this whole thread is mostly idiotic. It could have been an interesting topic but some seem to have other priorities. Which are quite transparent.
