Michael Totten's new podcast (8:17) from Metulla on the Israeli/Lebanese border paints a picture of tight-lipped Israeli soldiers crossing into Lebanon on foot. Now - after a seemingly endless and apparently pointless delay - Israel's ground invasion has begun.
A report from Stratfor (subscription) notes the unusually high level of infighting within the Israeli government, but does not ascribe the delay exclusively to that - or to any other known factor. "Something is holding the Israelis back", the report observes; "there is an aspect to Israeli thinking that we do not understand".
Maybe the events of the coming week will make things clearer.
