US President George W. Bush's visit to the Jewish state is "a black day for Arabs and Muslims," Hizbullah secretary general Hassan Nasrallah said Wednesday overnight. The Shi'ite cleric's comments were made during a speech on Hizbullah's Al Manar TV network. "Bush came to Israel to celebrate 60 years [of independence] of a state that has no right to exist," Nassrallah was quoted by Israel Radio as saying. Nasrallah also attacked the United States' policy towards the entire region and its readiness "to stand beside [Israel] even at the cost of a world war." "When Hizbullah kidnapped two soldiers, Israel had the right to destroy a whole country, but when a Palestinian defends his home and shoots Kassam rockets, the entire world protests vehemently," he said.
