I think US oil interests might have a thing or two to say about declaring Iraq not a country.

More specifically, the US interest in the Suez Canal. This critical piece of intercontinental infrastructure must be secured in order to efficiently transport material within the Mediterranean Ocean and out to the Atlantic. Also a BFD if you're moving military hardware through the region (like aircraft carriers).

Israel is a gun pointed at the neighboring states, intended to keep them in line. But if that gun keeps going off randomly, it no longer serves as a meaningful deterrent.
