The book in two volumes describes the evolution of Judeo Christianity and Islam and 1,300 years of warfare between them. Islam and Christianity follow gods with different characteristics and differing doctrines—free will vs. determinism. They were engaged in bloody conflict from 632 AD 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 has become progressively more serious ever since.
