It's a subject matter far from our original contention, anyhow. The bottom line is that your comparison between Japan and the Muslim world is off because Japan had reasons to embrace the West that the Muslim world does not. Your comparison is completely antiquated in light of recent history, that American occupation of Muslim countries has not gone as it did in Japan or Germany.
Speaking more broadly, Islamism is growing and more Muslims are voting for Islamist parties, for example. I posted a poll earlier that states the high level of support for Islamic law in several Muslim countries (but not in some others).
