Chevron Corporation wants to keep operating in Venezuela. That’s not an unalloyed good thing for the US, independently of what would be good or bad for Chevron. Neither is it an unalloyed bad thing for the US, independently of what would be good or bad for Chevron.

The long and the short of these are these. The bad for the US is that Chevron’s oil production, and presumably sales, would provide revenue that a Maduro regime badly needs.

The good thing for the US is that Chevron’s oil production and putative sales would serve as an important impediment, albeit not a barrier, to the People’s Republic of China moving in and exploiting that oil for its own purposes.

It’s the balance between the two that’s hard to gauge.
