Referring to the title of this post, the regime-change effort is totally led and controlled by the US. Even Abrams made clear Guaido takes orders from him.

The real problem with Venezuelan socialism is that it didn't go far enough quickly enough. It didn't usher in complete economic democracy.
As for letting the fascists run loose committing treason, is that legal under Venezuelan law?
Here's the goofy article: "Cracks appear in U.S. bipartisan unity on Venezuela."
