Will the US be more active in Venezuela after Juan Guaido attended the State of the Union as a guest of Trump?

The answer is: not really. Guaido was dissed, didn't meet with President Trump in Miami, could have a one on one. That looked really bad. The fact that he's at the State of the Union means that he's not in disgrace in the US, but he's lost a lot of influence in Venezuela. His popularity is about 50 percent of what it was, opposition getting divided. And Bolton, of course, is near the top of Trump's crap list. He was the guy that was driving a more assertive policy. Romney's probably on top of that list, right now though.
