"Israel's new chief of staff, an air force general, believed that most of Israel's future operations would be conducted from the air. Military leaders were convinced that with superior communications and air power they did not even need new U.S. "bunker buster" munitions to root out terror leaders in underground hideaways. Today, this vision of air power as a panacea has been shattered. Lt. Gen. Dan Halutz and his advisers have been stunned by the failure of Israel's air war against Hizbullah, which has shrugged massive air bombings on its headquarters in Beirut to maintain the rocket war against the Jewish state. "Air power is not the answer here," a senior officer said. 'You have to go from one Hizbullah [weapons] bunker to another. Some of these bunkers are seven meters deep and can't be destroyed by aircraft, even if you could find them."
