Still, no point to deny that Jack hit Joe, just because we like Jack better. We must find out exactly what happened. Once we get a clear view of events, we can engage in mediation with a reasonable chance of success. Otherwise we might step in on the side of the guy who drowned the hamster. The purpose of the noble speech on injustice and our duty to right it is to create fervor and excitement that will bring in contributions and volunteer party workers and voters.
Foreign evil means foreign danger.
Nothing brings in votes as fast as a good speech about danger from some evil ruler of some evil empire or kingdom. Everybody wants to be Luke Skywalker. Without foreign evil there can't be Luke Skywalker. Politicians need foreign evil, thus must demonize their opponents. It gives them great heroic lines, great speech opportunities, until election day.
