In 2003 John Paul II criticised the 2003 US-led invasion of Iraq, saying in his State of the World address "No to war! War is not always inevitable. It is always a defeat for humanity." He sent Pio Cardinal Laghi, the former Apostolic Pro-Nuncio to the United States, to talk with George W. Bush, the US president, to express opposition to the war. John Paul II said that it was up to the United Nations to solve the international conflict through diplomacy and that a unilateral aggression is a crime against peace and a violation of international law. The pope's opposition to the Iraq War led to him being a candidate to win the 2003 Nobel Peace Prize, which was ultimately awarded to Iranian attorney/judge and noted human rights advocate, Shirin Ebadi.
