I'm perplexed the author chose Merkel over Joan of Arc, given that the inspirational message is supposed to be aimed towards someone who is a combatant and not a politician. Granted, I don't think Joan of Arc was anything other than a flag waver, but the basic idea is that "The Strongest Witch" is physically strong and should be compared to a female soldier. Hell even Mulan would be a good choice, though the historicity of her is debatable.
