In the year 2010, the fiscal budget for the entirety of the United States' Military was $683.7B, this figure makes up over 20% of America's entire government budget. The USA's military budget reportedly rose in 2011 to $719B, and in 2012 to $729B. We can only expect a rise. As it is we spend more on our military than the rest of our UN allies combined.
Returning once more to the year 2010, America spent upwards of $50B producing vehicles of war, including the F-35 Fighter Jet & numerous variations of ballistic missiles.
A large proportion of this spending is to overseas producers. Currently, America cannot wage war w/o purchasing materials from possible enemy countries (China). Besides this detrimental fault, requiring USA made materials pumps tax-payer money back into America's economy.
