Hizbullah has had six years - ever since Israel withdrew from south Lebanon - to prepare for this climactic showdown. Instead of storing weapons and ammunition in vulnerable stockpiles, they are scattered throughout the south in natural caves, tunnels, and homes. Hizbullah officials say they have sufficient ammunition and high morale tofight for months.
Hizbullah's frontline fighters are battle-hardened veterans after fighting Israeli forces in the 1990s. They are armed with advanced Russian antitank missiles, which have proved deadly against Israel's vaunted Merkava tanks and use classic hit-and-run guerrilla tactics.
"Hizbullah is doing what it does best, harassing the enemy," says Timur Goksel, who served 24 years with the UN peacekeeping force in south Lebanon.
Indeed, Nasrallah has announced the launch of the "second phase of our struggle" in which his long-range rockets would "go beyond Haifa," Israel's third-largest city. Israeli officials have been bracing for possible rocket attacks on Tel Aviv, which would mark a major escalation in the conflict.
"If Hizbullah hits Tel Aviv, I think that Israel will totally wipe off the map Bint Jbail, Khiam, Tyre and Nabatieh," says Nizar Abdel-Kader, a columnist for Ad-Diyar newspaper and a retired Lebanese army general.
The stakes are high for Hizbullah, but it seems it can count on an unprecedented swell of public support that cuts across sectarian lines.According to a poll released by the Beirut Center for Research and Information, 87 percent of Lebanese support Hizbullah's fight with Israel, a rise of 29 percent on a similar poll conducted in February. More striking, however, is the level of support for Hizbullah's resistance from non-Shiite communities. Eighty percent of Christians polled supported Hizbullah along with 80 percent of Druze and 89 percent of Sunnis.
Lebanese no longer blame Hizbullah for sparking the war by kidnapping the Israeli soldiers, but Israel and the US instead.
The latest poll by the Beirut Center found that 8 percent of Lebanese feel the US supports Lebanon, down from 38 percent in January.
