Dept. of Low Expectations

In the course of an otherwise interesting op-ed, Victor Davis Hanson writes:

When our president references the 19th and 20th centuries, he apologizes for American sins but stays silent about the United States defeating Nazis, fascists, Japanese militarists and Soviet communists. The world hears contrition about Americans dropping the bomb to end World War II but never remorse from those responsible for Darfur, Grozny or Tibet.

Right. That's because we hold ourselves to higher standards than the regimes in Sudan, Russia and China. Is this really a problem?
