States / Cities Fund Military, Ruin Environment

Going on a book tour of the United States to events organized by peace groups will expose you to a national story that nobody is talking about nationally. Every town I go to complains that their city or state is funding a local weapons factory, that the workers in the factory are dying, and that the factory is destroying the water supply and the environment. Every city. Same story. Does anyone know this? Since when do cities and states fund the U.S. military?
