What are you referring to by "divisions"?
Stalin disregarding soft power in favor of military might for international diplomacy.
There is a massive loophole in that SCOTUS decision inasmuch as official acts are defined as legal ones. So if the President does something illegal, it isn't official. (We never saw that logic followed through because Cannon is a stooge and Garland took a nap for two years. But it's there.)
Note, too, that the absolute immunity is only for "core constitutional powers," i.e. those in respect of which his powers are "conclusive and preclusive." If the President has sole power in a domain, then the Congress doesn't have the power to criminalise it. Herego, absolute immunity for those. For everything else, it's closer to qualified immunity.
I can't say I really agree with the ruling. But that's mostly due to imparsimoniousness--I don't think they needed to make "a decision for the ages," they needed to narrowly rule on a case and controversy.
