Ariel Sharon was and remains a controversial figure generating all sorts of strong contradictory feelings in Israel and around the world. He is kind of like a Douglas MacArthur figure in Israel: military hero of the Yom Kippur War using "win at all cost" and controversial methods, disregarding authority, etc. Unlike MacArthur, Sharon obviously also had a successful political career generating further such contradictory feelings. The "Butcher of Lebanon" in the 1982 War later completely disengaged from Gaza. Unfortunately, the author notes he did not work enough with the Palestinians at the time and Hamas took over just as Sharon suffered his career ending stroke. This also scuttled possible plans to withdraw as well from the West Bank. What the Middle East might have looked like had Sharon lived we can only speculate but the author does just that in an interesting manner. The author also explores the possibility the whole disengagement from Gaza in the first place may have been connected to Sharon trying to turn the headlines away from growing alleged corruption scandals surrounding him. The alleged shady dealings of his son and cronies and the extent of Sharon's involvement is explored (good thing we don't have alleged shady dealings by unqualified political offspring here in the US...oh wait).
The author, a journalist by trade, clearly knows how to tell an engaging story and this book reached "can't put it down" status for me relatively quickly. He quickly goes through Sharon's childhood (perhaps too quickly as some reviews have noted) and then gets right to the action. He was able to also interview all the major players that were available and would talk to him (Netanyahu, Peres, Sharon's kids etc etc) so you get first hand perspectives on important events. The author clearly disagrees with Sharon politically, but like a great biographer, approaches the subject with a relatively objective lens. This is not a hit job, nor is it hagiography.
All in all, given Sharon's involvement from the founding of Israel all the way up to his stroke in 2006 and given the implications of how the pull out from Gaza occurred, which we are still dealing with today, I cannot recommend this book enough to learn the story and history of Israel and the Middle East Peace Process.
