"Prime Minister Ehud Olmert told the Winograd Commission that his decision to respond to the abduction of soldiers with a broad military operation was made as early as March 2006, four months before last summer's Lebanon war broke out." (thanks Emily, Said, and Regan)
And read this: "He said that as early as the first day of the war, U.S. Secretary of State Condoleezza Rice spoke with Olmert and asked that Lebanese Prime Minister Fouad Siniora not be undermined. Israel understood this to mean that Lebanese infrastructure should not be destroyed, even though the IDF had originally planned otherwise."
