You missed the point. Palpatine clearly demonstrates the "Have they ever thought about what they're going to do once they take it over"

And not only him, but in many series those that take over the world or even the entire universe are generally immortal beings who have a slight mental defect or some wannabe conqueror that gets his ass handed to him.
