In *any* history class, or in any history class taught by
government employees?
The classic debunking of this one is, I think, Henry Hazlitt's (not
sure if it originated with him, might have come from Frederic
Bastiat) story of the broken window. It's a simple homily from
economics, but if you understand it, then you understand what sort
of effect war has on an economy. Sorry I can't come up with a more
specific reference (I did run a few web searches).
If someone tried to foist this sort of propaganda off on a roomful
of children while I was present, knowing what I (think I) know now
and did not know when I was a child, I'd have a hard time controlling
my temper, I think.
