What's the desired strategic outcome here - to remove the incumbent president and his political party from power and replace it with one more favorable to US oil interests? And to do that without putting ground troops in to some Latin American Vietnam? Good luck with that.
It'll be the usual playbook: replace Maduro with a pet dictator. It won't go well for Venezuela and it's people, but since when did the USA give a damn about people?
Maria Machado? I thought independent observers mostly agreed she won the election?
