Seriously, are there any actual Neo-Nazi terrorist organizations which are a credible threat to anyone?

Ya. Pick just about any Arab country. They were all helping Hitler during WWII, they all have socialist economies like Hitler's, and they all hate Jews.

Point taken. But what I meant was are there any Neo-Nazi terrorist organizations out there whose membership consists of the "classic" Neo-Nazi. (I.E. Aryan skinhead, mostly Germans) I'd be seriously surprised if any such organization which posed a credible threat existed. As far as I know, street gangs and loudmouth protesters is as far up as Neo-Nazis go. Certainly nowhere near the level of "International Terrorism" which Al-Qaeda's at.
