User: i apologize for being away from the computer....as was the case when i took part in one of these exercises the other night, once again "nature called."  i have read in at least 3 places that part of the reason that world war 2 happened was because world war one, let's say. didn't "settle" things. that some countries came away unhappy.  germany in particular.  i don't understand it. so many llives lost in world war 1, and it had to be continued? i have even read that in effect there was only one world war with a separation by about 20 years. help me.
Assistant: A lot of historians argue that it’s impossible to make a case for or against World War II as a “necessary war” or “just war.”  There are some arguments in favor of the idea that one of the purposes of World War II was to establish a sense of justice and to help with post-war settlements, though in fact many post-war peace-treaties were not established until 1948-49.  Some historians argue that the problem of one world war is simply that it took place in a “nuclear age,” with the global ability to destroy all life on earth.  World War I was the war that created modern war technology.  So the technology and problems that led to World War I, were increased a great deal for World War II.
