The United States began combat operations in Afghanistan in fiscal year 2002 and in Iraq in fiscal year 2003. To finance those operations (and other activities related to the war on terrorism), the Congress provided $18 billion and $76 billion in emergency appropriations in those years, respectively. With the exception of a slight decrease in 2004, to $74 billion, funding has increased steadily each year, to a total of $165 billion for 2007. If the Administration's request for 2008 is funded in full, appropriations for military operations and other war-related activities in Iraq, Afghanistan, and elsewhere in the war on terrorism will rise to $188 billion this year and to a cumula- tive total of $752 billion since 2001.
