Ironic as the West winds down in Afghanistan an unusual pair of authors write this book 'The Arabs at War in Afghanistan'.

The authors are Leah Farrell, an Australian lady who was a CT analyst with teh Australian Federal Police, then dropped away from blogging to pursue a PhD and a book. Then:
Mustafa Hamid was among the first Arabs to join the jihad against the Soviets, and rose to become an influential figure, counting leading Afghan commanders and, later, senior Taliban and al-Qaeda figures among his friends. He was an eyewitness to and a participant in events that shaped not only Afghanistan’s history, but also the destiny of the Arab volunteers who joined in its liberation. After fleeing Afghanistan after 9/11 he spent close to a decade detained in Iran and has now returned to his native Egypt.
