Michael Oren has a new commentary on the 2006 Israel-vs.-Hezbollah war in Lebanon. It's worth reading, and it is not a rosy assessment at all. Oren calls the entire episode a disaster. At the time, I remember saying unhappily that Olmert's leadership was a catastrophe. This seems now to be the common view.
Oren's academic work on the Middle East, by the way, is always worth reading. I'm pretty sure I've recommended his excellent history of the Six Day War.
