In 2001, the US military budget is $293 billion a year. This is more than the combined budget of the next 15 largest militaries in the world. The US budget grows steadily in the years after 9/11, rising 40 percent to $427 billion in 2006. In 2008, it rises still further to $647 billion. This is considered about the same as what all the other countries of the world combined spend on military expenditures. [Rashid, 2008, pp. l]
