Regarding intervention in Venezuela, is that seen as a mistep in the US? In the rest of America it is considered as a win, except of course by Cuba (Cubans are the most, almost the only, affected)
Regarding politicians: Gustavo Petro was the most vocal protester; now that Trump told him in the White house to shut up, he is wagging his tail happily.
It successfully didn’t backfire on the US.
The operation in Venezuela could be characterised as an enormous success in the sense that it didn't seem to do anything and therefore was a big improvement on most times the US activates its military. But it was still a misstep in the sense that it keeps US aggression top of mind without achieving very much.
