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.

Yes, you are right. World War 1 did not definitively settle things, resulting in another conflict 20 years later, World War 2. There were several underlying causes of World War 1, including regional tensions, military alliances, imperialism and a nationalist fervor among all the countries involved. This lack of settlement and all of the issues that caused World War 1 meant there was fertile soil for another conflict. With countries feeling emboldened and believing more conquest or protection was necessary, another war, much more destructive than the first, ensued.
