The book is in two volumes and describes the evolution of Judeo-Christianity and Islam and the 1,300 years of warfare between them. Islam and Christianity follow gods with different characteristics and differing doctrine—free will versus determinism. They were engaged in bloody conflict from AD 632 until 1856 (Crimean War) when the Ottoman Empire became the "sick man" of Europe. It reignited with Egyptian encouragement backed by Soviet money, the arming of fedayeen terrorists in 1956, and the Six-Day War following Egypt's seizure of the Suez Canal, and it has become progressively more serious ever since.
