Trump has today, explicitly said that the US administration - specifically his administration - will run Venezuela, with boots on the ground, for as long as is necessary.
I was listening to the press conference and almost went back to edit my comment with a note about it. Honestly, coming out of that I have no idea if what is his saying is reality. As things stand and what we know, it doesn't make sense. We don't know about more troops currently on the ground. He said the VP has agreed to assist, but she is publicly saying very different things. I hate we are in a place as a country where we can't believe basic things about important topics our president says.
I think you are misquoting slightly. Trump said he's not afraid of putting 'boots on the ground' in the country if necessary, not they are confirmed.
Also in the Q&A he mentioned this was mostly targeting the protection of the oil extraction/American companies taking over, not the rest of the country.
(tho not sure how much we can really trust what he says)
