It was the STIMULUS of the money the US spent on that war that brought us out of The Great Depression... killing people didn't do it, but when you say WWII did it, that's what it sounds like.

Why can't we just spend money on good things for we the people? Take the amount that was spent on WWII and bring it up to what it would cost today, then spend that money on things we need... like roads and bridges and schools... you know, the stuff we need?

Because we are only motivated to spend that kind of money on death! Why can't we be motivated to spend it on LIFE??
