I don't think I've seen it raised yet, but wouldn't oil sanctions against the US and EU be a logical step for the OPEC powers to take, especially as more details of the Final Solution in Gaza come out and their populations get more insistent?
This time it feels like it could actually end the empire, since apparently it's too hollowed out to fund the genocide and a proxy war at the same time. 
not sure what KSA will/won't do or if oil is going to be the trigger (probably), but this situation, the threatened prosecution and explicit demonization of palestinian sympathies, the probably deployment of a 2nd carrier group, the existing framing (by law) of BDS as "anti-semitism" and the apocalypse cult fervor of evangelicals for the israeli government feels like the imperial project is pushing all its chips in to buy the pot again.
i know the extremely online libs and evangelicals are committed and the bot farms are running on overdrive, but when ukraine-russia happened, the US effectively sidestepped any repercussions and the let the EU take the economic hit on the chin. even so two years on, seems like the US has all but walked out on that one. if gas prices go up in the US due to some OPEC action or war disruption, i don't see how the machine can short circuit war weariness without some kind of 9/11 type of deal. the republicans might not have the support for it among their base, now that their base is like 20% Qanon-JFK Jr. cult weirdos getting The Protocols tattooed to their necks. that and the supreme court being Lochner-era 2.0 seems like the only thing keeping the DNC alive.
i think whenever some nominal ally (like KSA) sees the weakness (like maybe prison trump wins after 6 months of BidenWar lol) and makes a move to get concessions out of the US for continued loyalty, there could be a feeding frenzy of "allies" looking for assurances at a time when there's nobody behind the wheel.
