Is nuclear war planned as an extension of the downward spiral involving the tidal power outages?

Fortunately, we can tell you that this is not a primary objective. The whole key to working within the alien agenda is to intrigue them to maintain the human presence as a kind of experiment, to see what will happen in their absence so they are no longer wanting a draconian mass execution in the near term. And that is what creates the potential to keep things going and have enough breathing room to complete human healing in time to allow a grand Ascension prior to the return of the extraterrestrials.
