According to Stratfor: "The ground war has begun. Several Israeli brigades now appear to be operating between the Lebanese border and the Litani River. According to reports, Hezbollah forces are dispersed in multiple bunker complexes and are launching rockets from these and other locations.
Hezbollah's strategy appears to be threefold. First, force Israel into costly attacks against prepared fortifications. Second, draw Israeli troops as deeply into Lebanon as possible, forcing them to fight on extended supply lines. Third, move into an Iraqi-style insurgency from which Israel -- out of fear of a resumption of rocket attacks -- cannot withdraw, but which the Israelis also cannot endure because of extended long-term casualties. This appears to have been a carefully planned strategy, built around a threat to Israeli cities that Israel can't afford. The war has begun at Hezbollah's time and choosing. '
