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.

World War I was an intra-European conflict that began in 1914 and ended in 1918, whereas World War II, also known as the Second World War, was an international conflict that lasted from 1939 to 1945. It is correct that many of the countries and/or their imperial aims which were left unfulfilled at the conclusion of World War I, provided a foundation for the aggressions of World War II; Germany and Italy being prominent examples. However, some scholars also argue that there were significant differences between the two conflicts including their scope, intensity and strategic objectives.
