Some comments about the Venezuelan oil.
1) The tankers being intercepted would appear to be empty, or near empty. So the value of any cargo, i.e. the oil they were pirated for by the USA, is effectively zero. Certainly the old rust-bucket tankers themselves would have value only by being scrapped on the beach in Bangladesh. They are not worth money spent by the US to illegally seize them. Trump has turned the US Navy and Coast Guard into a bunch of bumbling, failing pirates - a laughingstock.
2) The original major buyers of Venezuelan oil - Russia, Cuba and China - are on Miller's naughty list of socialist commie countries. So what is going to be the priority for Don? Not selling the oil and sticking to Miller's naughty list? Or selling to them, thereby looking hypocritical (no problem for Trump personally), and also helping further Russian, Cuban and Chinese influence and prosperity at home and abroad? I'm betting he will sell. He
really covets the money more than anything.
3) Would Russia buy oil from the USA when it has ample reserves of its own, and reasonable infrastructure to extract and process it? Would Pootie do Donnie a favour? Sure he would! All Donnie has to do is...anything Pootie asks of him!
4) The Venezuelan oil is not really going to be very valuable because it has to be transported to the USA to be processed. That takes time and money. And it's a low-quality product suitable only for asphalt, and the main customers for asphalt are not the USA. Exxon have just said that it probably won't be worth them investing in that whole shemozzle.
5) Exxon also said there's no viable infrastructure in Venezuela for further oil extraction, or it's so outdated it is unprofitable. It would require billions of dollars investment from scratch to re-establish any economical extraction, and they aren't up for that just now. So the supply is going to run out and production dry up soon (for wide values of "soon"). The Trump invasion simply killed off an ailing, crumbling, low-profit operation.
Summary: Everything Trump touches turns to ◊◊◊◊. The Venezuelan debacle is just the latest, on a global scale.
