This is the classic thing to do with a foreign enemy.

You demonize him up really, really good. ¬†That way, YOUR team knows that YOU’RE the GOOD GUYS, and those other guys don’t love their children and defame celebrities that you admire, and also they don’t wash properly and eat food that isn’t good at all, when they eat, which isn’t often, and they have bad teeth, too, partly because of the food but partly because of lousy genetics which people from HERE don’t get because YOUR people floss like respectable, civilized people. ¬†Well, not every day like you’re supposed to, but sometimes floss. More than bad foreigners who slap the queen with disguised fish do, anyhow.
