What if all of Yuri's Revenge ending is full of lies? What if Yuri's forces managed to enter the Time Space to save him from the Chrono Chamber? It will result in a time paradox, creating a new timeline that we can't predict. With an altered past, that's where a new war will begin. A new future will be forged, or a new conqueror will be born. Do what you must.
