Military spending: The military budget of the United States during FY 2009 was approximately $683 billion in expenses for the Department of Defense (DoD) and $54 billion for Homeland Security, a total of $737 billion.[40] The U.S. defense budget (excluding spending for the wars in Iraq and Afghanistan, Homeland Security, and Veteran's Affairs) is around 4% of GDP.[41] Adding these other costs places defense and homeland security spending between 5% and 6% of GDP. The DoD baseline budget, excluding supplemental funding for the wars, has grown from $297 billion in FY2001 to a budgeted $534 billion for FY2010, an 81% increase.[42] According to the CBO, defense spending grew 9% annually on average from fiscal year 2000-2009.[43] Much of the costs for the wars in Iraq and Afghanistan have not been funded through regular appropriations bills, but through emergency supplemental appropriations bills. As such, most of these expenses were not included in the budget deficit calculation prior to FY2010. Some budget experts argue that emergency supplemental appropriations bills do not receive the same level of legislative care as regular appropriations bills.[44]
