Probably not - Miller's a libertarian with a strong love of America.
He wants to write a comic book in which Batman fights al-Qaeda, after all.
Concerning Frank Miller - I watched a history of comic books program a few years back. I think it was Denny O'Neil - I could be wrong - who said about Miller that he would be even better if he didn't hate comic books so much. The person saying this never elaborated on it. I thought it a strange statement considering some of the fantastic stuff Frank Miller has done. His revamping The Batman turned that character around and ever since, every writer and artist has worked from Miller's perspective. His second take on the Dark Knight was - IMO - not as good as the first.
