I recommend reading the book (Ian Johnson's A Mosque In Munich: Nazis, The CIA, And The Rise Of The Muslim Brotherhood In The West) because it is the first (and, AFAIK, so far only) study where all the "tangentially related links" are explained in context. Johnson did an excellent job of perusing West German and newly declassified CIA documents, as well as tracking down and interviewing surviving participants of the events. It is not something you can credibly explain in one post.

I guess I don't understand the writer's, or your, focus on the fact they were Muslim when the CIA, and adversarial intelligence agencies generally recruit opportunistically from any disaffected groups.

Because that is what the book is about. Specifically, about the history of the Islamic Center of Munich, regularly attended by Mahmoud Abouhalima, the 1993 WTC bomber, and Al Qaeda co-founder and bin Laden mentor Mamdouh Mahmud Salim. I don't know what you are trying to imply. As suggested previously, read the book.
