Do you feel that the costs of the war 2, both in human lives and financially, was worth fighting the war?

this is an opinion, so i really don't think what others respond should have an effect on your personal answer. however, no, i don't think the costs of ww2 were worth the casualties and financial loss because since it grew gradually, there was a generous amount of time to negotiate beforehand. however, i'm sure a lot of people disagree with this. see what other have to say.
