I really don’t see the Saudis as being upset with Brandon. They’re back to their market manipulating ways due to high oil prices and instability of reserves here in the US. Trump had managed our oil energy policy well, and the Saudis did not like that.
Trump did manage our oil well. Still, there was and is lots of global demand for energy. Whatever minor annoyance the Saudis had with Trump making America more energy independent was more than offset by him:
A) being quite openly and clearly supportive
B) dumping the idiotic Iran deal
C) sending Soleimani straight to hell
D) He also backed them in Yemen and sold them weapons
E) He also lined up Israel and several more Arab countries.....Israel is a valuable ally for them against Iran
MBS has made it clear he much prefers Trump.
