Myanmar's Aung San Suu Kyi

A portrait of Nobel peace laureate Aung San Suu Kyi is held during a torchlit parade to a hotel where U.S. President Barack Obama was staying in Oslo December 10, 2009. The United States must uphold moral standards when waging wars that are necessary and justified, Obama said on Thursday as he accepted the Nobel Prize for Peace. In a speech at the award ceremony in Oslo, Obama said violent conflict would not be eradicated "in our lifetimes", there would be times when nations would need to fight just wars and he would not stand idle in the face of threats to the American people.
