I don't think the US is going to occupy Venezuela.
It has about 30M people. It's about 900,000 km², about the size of Texas + Oklahoma (or Spain + France).
From everything I've read, the US has about 15,000 troops in the Caribbean.
Compare the invasion of Iraq in 2003 -- about half the area, slightly smaller population. The US deployed about 150,000 troops to the area - 10x what are currently in the Caribbean.
