Steady Growth Through the 2000s and 2010s
In the late 1990s, under President Clinton, U.S. defense spending sat around the mid-$500 billion level in real terms.
Spending rose significantly in the 2000s during the Bush years amid the wars in Afghanistan and Iraq, reaching levels above $900 billion before 2010.
Continued high budgets carried throughout the Obama administration, driven by ongoing post-9/11 commitments and modernization efforts.
