U.S. President George W. Bush mourned the death of the 3,000th U.S. soldier in Iraq, the White House said on Sunday, but cautioned war weary Americans that no quick end was in sight to the fight against terrorism, according to Reuters. "The president believes that every life is precious and grieves for each one that is lost," said White House spokesman Scott Stanzel. "He will ensure their sacrifice was not made in vain."
