So far, Hoplite, of all the wars and all the atrocities we committed, we still don't have a publically recognized and labeled official war criminal on record. Not one.
Countries deny their atrocities, but we all know that none is without sin. Self-accusation is the first step in repenetence, and as far as I am concenred there is not a single country in this world that can rise to that occasion.
Japan grudgingly apologized to the Chinese 60 years after the fact. That didn't stop us from keeping close ties with Japan. It Germany a while too, to apologize to Poland (Willy Brandt), and even then it was considered a scandal among Germans of the late 1960's.
Get off your high and righteous horse and wash your own hands first. Then pontificate to others.
Everybody needs something to believe in. Unfortunately some of us set our sites extremely low and feel compelled to spew our shallow blather all over the shoes of us that know better. *Shrug* I suppose we should give him points for persistence.
