So it was wrong. But clearly not wrong enough to warrant erasing America and its wealth from existence. Saying sorry and expressing regret is cheap. Actual action is expensive.
As an aside, I wonder what the psychological effects are from growing up in a nation where the public discourse is all about how the nation was unjustly founded. If a significant part of the next generation believes that America's historical foundations are rotten to the core and that its existence is a tragedy, what happens next?
