You must read this book anon if you are interested in the crash and the investigation and those responsible for it and much of the terrorism around the world. He lost a loved one in that crash and he himself almost died in a terror attack. First half of the book deals with the crash and investigation and reaches a conclusion. It was terrorism like many others around that time.
Second half traces back the group responsible. For that you have to go back to WW2. Many of the Nazis went to two places. Argentina and Egypt. You cannot understand the middle East and south America without getting those connections. His research is thorough not missing a beat.

General Flynn endorses this book and is a friend of Saul. Let's hope those dead from the crash get justice.
In the last pic related is a list of Nazi's that fled to Egypt, converted to Islam and changed their names. You cannot understand Iran, Iraq, Syria, turkey etc without knowing the connection. It is no coincidence Obama gave his first massive Speech at Cairo University. Also that Brennan did spend time there as well in the late 70s.
