You might think a fifth of the federal government's total spending is a lot to put into defense. But in comparison to some earlier periods in our country's history, it's actually a smaller share. During
President Ronald Reagan's defense buildup, the military claimed 26 percent of the budget. And at the height of the
Vietnam War in 1968, 46 cents of every tax dollar Americans paid was for defense.
Of the remaining discretionary spending, the Department of Homeland Security claims about 1.5 percent of the budget, or $43 billion. Foreign aid spending, though it raises the ire of many taxpayers, accounts for just half of one percent and is likely to be reduced by Congress even further.
