GAZA CITY, Gaza Strip - U.S. President George W. Bush is the enemy of God and Islam, the new Hamas chief in Gaza said Sunday, declaring that God's war against the United States and Israel was ongoing.In a speech at Gaza's Islamic University, Hamas leader Abdel Aziz Rantisi said he was not surprised that the United States vetoed a U.N. Security Council resolution condemning Israel's assassination last Monday of Hamas spiritual leader Sheik Ahmed Yassin. "We knew that Bush is the enemy of God, the enemy of Islam and Muslims. America declared war against God. Sharon declared war against God and God declared war against America, Bush and Sharon," Rantisi said. "The holy man (Sheik Yassin), he said the war of God continues against them and I can see the victory coming up from the land of Palestine by the hand of Hamas." Immediately after the Israeli missile strike that killed Yassin, Rantisi and other Hamas leaders threatened to retaliate against the United States, Israel's staunchest ally. However, a few days later, Rantisi backed down from the threat, saying Hamas would only be active in the West Bank, Gaza Strip and Israel.
