World War 2 cost more than World War 1 in terms of lives and monetary cost and post-war reparations because the war was conducted in more nations, involved more people and involved the expensive develpment of the atom bomb. It also required the development of new ships, planes, subs, armament, vehicles, and the production of millions of uniforms and gear. Medical service had dramatically increased and improved too so that cost was far higher than in World War 1. The cost of making things was higher twenty plus years after World War 1 too.
