Cuba is entering its fourth straight day of a nationwide power outage. Is this just an example of how shaky their infrastructure has been since the days of Fidel Castro, or is it actually related to the sinister power outage you predicted would take out U.S. electrical grids, one by one, and then move around the world?

You have already seen intuitively that this is a warm-up exercise. It can be a useful point of reference when more developed countries with greater affluence are seen to have a similar breakdown of basic services such as an electrical grid. No country wants to go back to the pre-electric era. Some would not survive those circumstances given the huge reliance on electrical power for all modern conveniences and often even home heating. So this is, indeed, a preview of coming attractions to regions near, and likely including, most people as victims or witnesses to the handiwork of the Extraterrestrial Alliance.
