What's the Co-relation between US defence spending, fiscal deficit and state of economy?

The relationship between defense spending and economic growth in the United States has both negative and positive effects. Negative effects typically mean a greater tax burden, a bigger budget deficit, perhaps inflation, and maybe a decline of social welfare spending on programs such as public health and/or education.

Other experts maintain that defense spending stimulates the U.S. economy because it creates more jobs. Increased defense spending also helps provide security, which is critical for economic activities and may help attract greater foreign investment. Still other experts have studied these relationships and believe there is no statistically significant direct relationship between defense spending and economic growth.
