It is important to note that these are just predictions, and there is no guarantee that these countries will be destroyed or survive in the event of a third world war. Ultimately, the outcome of a war is determined by many factors, including the military capabilities of the countries involved, the political will of the leaders, and the unpredictable nature of human events.
