Perhaps more interesting than any review I could write is Michael Scheuer's "review of reviews" here https://www.lewrockwell.com/2005/02/michael-scheuer/imperial-hubris/. He strikes me not as an appeaser, but as a patriot disappointed in the path his country has taken.

This book gives those of us interesting in The Crusades another view of the times and what the thinking was of the Arab leadership.  I found the book fascinating.  I never would have thought the Arab world at the time was so fragmented or that they considered the Crusaders to be mostly unwashed heathens.  Also many Muslims today consider the war on terror to be a continuation of those Crusades.
