Postwar Policies... What do you think changed as a result of the war in regards to: -Individual nation's policies -Relations among the great powers...

The end
ofsignified the end of massed warfare
-- never again will all the resources of one country or
nation be pitted en
masse against another -- once the Bomb existed, all-out warfare was a thing

of history.  WWII altered warfare.  Since that time throughout the world, there has been
armed
conflict, but that was contained by the aforementioned superpowers.
 It's interesting to see now
the rise of "indiscriminate" warfare, or
terrorism, as the other forms of warfare
expression have been
neutralized.
