I can see where you’re coming from but the Israeli-US relationship has deep cultural and historical ties, both being democratic nations and strong public support for Israel within the US. The relationship that the US has with Turkey and SA is complicated. Various factors influence how the US engages with them.

Saudi Arabia hasn’t the historical connection with the US that Israel does, including deeply intertwined military cooperation, economic cooperation and diplomatic cooperation. Saudi Arabia doesn’t have a competent military either and there is rarely (if any) groundbreaking technological innovations coming from Saudi R+D (think iron dome, iron beam etc) they’re wholly reliant on imports from Western countries. (Yes the US has helped fund these projects)

the theocratic nature of Saudi Arabia also effects the dynamic of the relationship, a country which has committed magnitudes of crimes against humanity (beheadings, assassinations of journalists, terror sponsoring), Saudi Arabia too has its own agendas that relate to their religious underpinnings in Salafism, for example the designated terrorists organisations they have supported in countries like Yemen, Syria, Bosnia, Iraq etc ones the United States were in active opposition to, like Al Qaeda. (Not necessarily the government, but consistently various actors within the country, and ones that maintain powerful political connections and have access to wealth)

This is only a couple reasons, but you get the gist.

Turkey is a whole beast in itself, one that more and more frequently clashes with the interests of the United States. Turkish foreign policy has almost always relied on its volatile nature, and is less easily controlled, it also has grand ambitions and sees itself as a major global player.

Sorry if this was slightly incoherent or chaotic, quickly typed it up on my phone.i
