You seem to conveniently be forgetting a basic fact: Germany unleashed a
vicious all-out war machine to win at all costs. The United States has yet
to fight a war without severe political constraints dictating what it can
and cannot do. If the US waged Nazi or Soviet-style war and simply employed
its capacity to lay waste to whatever it chose conventionally we would have
produced the sort of 'victories' you see to prize so greatly. Fortunately,
we don't do that since, unlike you, we're not Nazis.
