He's called Captain America. Do you think he would become president of Germany?
The Ultimate books have a better track record than the regular books in paying stuff off and going with ideas. That's the sad part. Everything in the regular Marvel verse seems to be going with a premise and not knowing where its going. If they did Spider-man's unmasking in the Ultimate verse, they would do it and it would be a story. They killed him off, but they did that with the 'original' one and he instantly came back to life. It's the best thing you can say about the Ultimate line.
