Perhaps the timetable for them could've been extended, but when literally one of the largest nuclear power companies in the world prefers renewables, and balks at the cost of opening a nuclear powerplant without significant government guarantees and subsidies, that should tell you something. The nuclear argument is usually fuelled by the mining lobby. Even China, who does not care for public opinion, and has an active nuclear stake for military purposes, prefers renewables. The only argument for Germany was the when was the appropriate time to shut down the reactors, not that it shouldn't have been done.
