How about the entire Interstate road systems in America that allowed the massive boom of the middle class.

Would we have the space age polymers, fiber optics, radar, comfortable mattresses & otherwise we take for granted on a daily basis, if it wasn't for war?

And what about Tang?

It seems to me that war (controlled war, not anarchy & terror) is not only a good thing (in the long run) but also necessary to the long term future of human kind.

Feel free to add on another development directly linked to warfare.
