If the US government was at least somewhat rational, I would say the chances are low because their military is already over-strained, over-stretched, under-maintained and under-supplied to a level that is just not remotely sustainable and they cannot afford yet another front, not even against the weak Venezuelan military.

But the US government and their Pentagon lackeys appears to be a bunched of fools and clowns with a gift for wasting resources on obviously doomed projects and have it all backfire in the worst way possible.
