Are American Muslims Fighting in Iraq?

This is an honest question from a man (cartoonist) in the street; not so well informed. It is directed to Muhammad, or Andrew, or the media, or whoever is smart. I really do not know the answer.

I understand that Iraqis are 97% Muslim, 60%-65% Shi’a, and 32%-37% Sunni; and 3% are Christian or other.
