I just saw a bit of Carter's speech after he was presented with the Nobel Peace Prize.
War may sometimes be a necessary evil. But no matter how necessary, it is always evil. Never good.
War is always evil. Never good?
The Revolutionary War? Evil or Good?
The Civil War? Which resulted in the end of slavery. Evil or Good?
World War II? Which stopped the complete genocide of the Jews in Europe. Or the War in the Pacific that halted the systemic murder of Chinese and Filipinos (among many others) by the Japanese. Evil or Good?
Carter has done some admirable work since his presidency, especially with Habitat for Humanity, but it's statements like this one that demonstrate why he was soundly defeated by Ronald Reagan.
During times of war, be it the Cold War or the War on Terrorism, America needs leaders who understand good and evil.
