Al Qaeda Number 2 Ayman al-Zawahiri has claimed that the United States has achieved nothing but failure and defeat during its 5-year invasion of Iraq. He said the Bush government would give the same to new US government. In an audio message released on militant's website from Cairo, Al Qaeda's leader said at the behest of the US commander in Iraq, Lt. General David Petros, President Bush delayed the withdrawal of US troops from Iraq and now he wanted to cover failure of his policies.
