Economics and National Security [PDF ebook] 

The global financial crisis and recession have highlighted the trade-off between spending to protect against external threats and spending to provide jobs and income for citizens at home. This book illustrates how disparate parts of the U.S. economy affect the security of the nation. Security is achieved not only by military means but by the whole of the American economy. In national security, the economy is both the enabler and the constraint.
