That has happened and not a lot came of it. Venezuela nationalized American oil projects under Hugo Chavez. If by hell breaking loose you mean law suits I guess so.
The motive for recent boat bombings is supposedly stopping illegal drugs. Though IMO it has more to do with distracting from the release of certain human trafficking records. This US administration seems bent entirely to the will and ego of one person.
(Which isn't to say the US has clean hands. Our list of attempted coups in South America is long.)
People voted for Chavez and then (at least once) for Maduro because the massive inequality was unsustainable. If the US had accepted that and worked with them instead of against them, maybe we'd be in a different place right now. But the interests of oil companies always come first, sadly. (obviously this does not absolve the Venezuelans from their responsibilities.)
