The Israelis did not bomb southern Beirut because they thought there were bonkers there or weapons. They bombed southern Beirut because they wanted to get rid of and actually kill young men that would fight on the side of Hezbollah. What happened in Beirut was an extermination and genocide of the poor. According to the Washington Times :
“U.N. humanitarian aid coordinator Jan Egeland condemned the Israeli air strikes as "a violation of international law" after touring a neighborhood in southern Beirut that had been largely leveled by air strikes. He said about $100 million was needed immediately to provide relief to an estimated 600,000 displaced Lebanese.
"It’s terrible. I see a lot of children wounded, homeless, suffering," said Mr. Egeland, who visited a Hezbollah-dominated slum that was once home to several thousand people. "This is a war where civilians pay a disproportionate price in Lebanon and northern Israel. I hadn’t believed it would be block by block leveled to the ground."
With the carpet bombing of Lebanon the Israelis have effectively avenged themselves and gotten revenge for the holocaust. They are walking in the shoes of Hitler and the Nazis. They have killed the poor and the hopeless of Lebanon, the equivalent of U.S. Katrina victims, but in this case the victims never had a chance to get out as block by block their homes were leveled to the ground with I am assuming some of them in their homes and I am seriously doubting whether the casualty count on the Lebanese side is correct.
