Based on how willing those powers have been to sit by and watch the Palestinian Genocide, I think they have been sufficiently brought to heel or vice versa have brought the US to heel to the point that a shocking silence has already prevailed.
The ducks already had to be brought in line for the Palestinian Genocide, this hardly feels like a speedbump in comparison for a lot of countries in the middle east I suspect.
It also might honestly be that as angry as the rest of the world is, the Ukrainian war has re-emphasized how far ahead US military power and doctrine is especially in dynamic environments and OPEC just doesn't have the basic military capability to counterbalance. Seeing Russia claim to send SAMs and associated crews to Venezuela as if Russia even has enough air defenses to defend Moscow.... It doesn't help that a lot of the best equipment Saudi Arabia and such have were bought from the US and neither China nor Russia can really claim to be on the level US and European militaries are at in sophistication and actual war experience (though obviously this is variously true and changing at a very rapid rate along many dimensions see the EDGE group and such, I doubt this is the full answer).
Or maybe, and this is MOST likely, OPEC is just used to dealing with washed up dictators that are quickly outliving their usefulness to their supporting power structures around them and knows one way or another Trump has an expiration date so escalating conflict makes less sense than posturing to cut the US out of favorable positions and biding their time until the US has a change in rulers to someone more rationally bribable again. That is what I would do, these strikes and actions against Venezuela are politically unsustainable in the US because they are so blatantly wrong and outside domestic interests.
If there is anything I am sure about it is that the children of politicians are largely useless.
Statistically it is a far superior choice to literally pick a random person off the street.
