The crisis-racked Venezuelan government has roundly rejected an offer by U.S. Secretary of State Mike Pompeo to drop sanctions in exchange for a political transition. It follows a similar proposal by opposition leader Juan Guaidó, and envisages both him and President Nicolás Maduro stepping down to make way for a five-person council. Parliamentary and presidential elections would come 6-12 months later.
How could such a proposal succeed? It would likely need to guarantee Maduro's safety, as well as win backing from skeptical parties like Russia and China.
